What is the best dry pet food for cats with hyperthyroidism?

Hill's Prescription Diet y/d Thyroid Care Dry Cat Food is specifically formulated to address the dietary needs of cats with hyperthyroidism. This makes it a top choice for managing this condition. It offers a convenient and effective solution for pet owners seeking to control their cat's thyroid hormone production. This specialized diet is clinically proven to reduce thyroid hormone levels within three weeks when fed as the sole source of nutrition. By limiting the intake of iodine, a key component in thyroid hormone production, y/d Thyroid Care helps regulate the overactive thyroid gland. In addition to its therapeutic benefits, this diet is nutritionally balanced to support overall feline health. It provides essential nutrients, vitamins, and minerals to ensure your cat receives the necessary nourishment while managing their hyperthyroidism.

How can I control my cat's thyroid?

Controlling your cat's thyroid condition, particularly hyperthyroidism, typically involves medication, diet adjustments, or more invasive treatments like surgery or radioactive iodine therapy. Stephanie Howe, a DVM from Florida, says that methimazole is a common medication used to manage hyperthyroidism in cats. It works by reducing the production of thyroid hormones. To effectively control your cat's thyroid with methimazole, it's essential to administer the medication as prescribed by your veterinarian. This may involve giving the medication orally once or twice daily. Regular veterinary check-ups are crucial to monitor your cat's thyroid levels and adjust the dosage if necessary. In addition to medication, dietary changes may complement the treatment plan. Certain diets formulated for thyroid health can support your cat's condition and overall well-being. While medication can effectively manage hyperthyroidism in many cases, it's essential to monitor your cat for any side effects or adverse reactions. Regular blood tests and check-ups are vital to assess thyroid hormone levels and ensure your cat's health and comfort.Reference:https://www.petmd.com/pet-medication/methimazole-tapazole-felimazole

What do you feed a cat with thyroid problems?

Cats with thyroid problems require a carefully managed diet to support their health. Opting for canned or raw diets is recommended. These options are preferable because they offer a higher protein content from animal sources, which is essential for cats, especially those with thyroid issues. When selecting canned or raw food, it's important to choose varieties that contain minimal fruits, vegetables, or grains. Sherry Lynn Sanderson, a DVM from the University of Georgia, highlights that cats are obligate carnivores, meaning their diets should primarily consist of animal-derived proteins. Fruits, vegetables, and grains are unnecessary fillers for cats and may not provide the essential nutrients they need. Reference:https://www.msdvetmanual.com/management-and-nutrition/nutrition-small-animals/overview-of-nutrition-small-animals

What organs are affected by hyperthyroidism in cats?

Hyperthyroidism in cats primarily affects the thyroid gland, leading to an overproduction of thyroid hormones. However, the effects extend beyond the thyroid itself. Hyperthyroidism can result in systemic consequences, particularly affecting organs sensitive to thyroid hormone levels. Commonly affected organs include the heart, leading to cardiac complications such as hypertrophic cardiomyopathy and arrhythmias. Additionally, kidneys may suffer from reduced blood flow, exacerbating any pre-existing renal conditions. The eyes may also be impacted, with symptoms like high blood pressure-induced retinopathy. Hypertension accompanying hyperthyroidism further exacerbates these issues, potentially damaging various organs, including the eyes, kidneys, heart, and brain. Therefore, timely diagnosis and management of hyperthyroidism in cats are crucial to prevent or mitigate these systemic complications.

How do you treat a 17-year-old cat with hyperthyroidism?

Treatment options for a 17-year-old cat with hyperthyroidism usually include anti-thyroid medications like methimazole and tapazole, which help regulate thyroid hormone levels. These medications are typically administered orally and require ongoing monitoring for potential side effects. Richard Keeler, an experienced pet parent, recounted how his cat Joshua responded well to tapazole. Initially struggling with the bitter taste of the pill, Richard discovered that tapazole could be compounded into a topical lotion for application. Despite Joshua's initial objections, he soon began to feel better with the topical medication. Richard emphasized the effectiveness of this method, highlighting how Joshua even reminded him if he missed a dose. Surgery to remove the thyroid gland (thyroidectomy) is an alternative, albeit with risks due to the cat's age. Specialized diets and radioiodine therapy are other options, with the latter considered the most effective long-term treatment.Reference:https://www.quora.com/How-effective-is-thyroid-medication-for-a-seventeen-year-old-cat

How long can a cat live on thyroid medication?

Most cats with uncomplicated hyperthyroidism, when treated with thyroid medication such as methimazole or radioactive iodine therapy, can expect to live several years post-treatment. The effectiveness of thyroid medication in managing hyperthyroidism largely depends on the cat's overall health. The severity of the condition and how well the medication is tolerated also plays a role. Thyroid medication helps to regulate the cat's thyroid hormone levels, restoring them to a normal range and alleviating the symptoms of hyperthyroidism. With proper treatment and monitoring, many cats experience significant improvement in their quality of life and can live comfortably for several more years. However, it's important to note that thyroid medication does not cure hyperthyroidism, it manages the condition. Regular monitoring of thyroid hormone levels, along with periodic check-ups may be necessary to ensure the continued well-being of the cat. Additionally, some cats may eventually require additional treatments or develop other health issues that can impact their longevity. Therefore, while thyroid medication can effectively manage hyperthyroidism and extend a cat's lifespan, individual outcomes may vary.

Good, but I wish the kibbles were smaller

Overall, this product works and my cat doesn't mind eating it -- granted it's not her absolute favorite -- but I wish the kibbles weren't so big. My cat is rather small in general and sometimes it seems she has a hard time getting them down. She will gulp somewhat strenuously or sometimes shake her head and occasionally she even seems to attempt to clear her throat when she's done eating. I tried softening it with water but she then has no interest in it and it's unfortunately extremely difficult to break the kibbles into smaller pieces. Cats usually swallow dry food whole and these are pretty big to be going down for their size.

Reduced our cat's T4 value to almost normal!

Our 15yo cat was diagnosed with hyperthyroidism at age 10. Radiation treatment (very expensive!) worked for a couple of years but soon his T4 was back up over 250. (Tablets were out of the question, as he had a severe reaction to them after a few days). The vet suggested the Hills yd cat food. We hoped he would like the taste, and he loves it! Last blood test showed his T4 down at 68: just 8 above the upper limit of normal! We are thrilled.

Changed ingredients

The thyroid care dry food has been helping my cat and has been the only feed I had been able to feed without him spewing. Until today when we fed our cat a newly opened bag and spew everywhere within 2hrs of feeding. Checked out and compared the new bag of thyroid care dry to the old bag of thyroid care and the ingredients have changed! So now back to square one.

Great for getting bloodwork back to normal

My senior cat had mildly elevated t3 & t4 and elevated kidney values. This food combined with the wet food brought it to a normal range. His energy is back to normal or thst of a younger cat.

When will it be available again?

Can you provide any estimate of when the y/d products will be available again? It is challenging to make medical decisions for your pet with no idea of if/when this will return. It just seems irresponsible, heartless, and contrary to your statements to pretend there are easy alternatives for the cats needing this food.

When will this be back in stock?

Our cat has done well on this diet. But now she is back on her meds because it's been out of stock everywhere for so long. It is much more expensive than her medications, but it was worth it for as long as it was available. When will it be back? And can we trust Hill's not to drop the ball again?

Unfortunately, I need to since it is necessary for my cat

This food has been life saver to my precious fur baby. She was diagnosed with Hyperthyroidism at her mature age. Unfortunately, she had a bad reaction to medication. This food was an amazing alternative! The price point is high, to say the least, for our family. But she is worth every penny! Running into a backorder situation is the most stressful thing a pet parent can go through. How do I feed her? What do I do? Yes, we have an amazing vet, but this is the ONLY option we have. Yes, I ordered early so that I would have extra on hand. Yes, I have called EVERYWHERE. Yes, I looked online at all the options that I could find. But now I am down to the last few days of my last bag. So, I called your customer service agent to find out an ETA. I received what sounds like a blanket statement, a script, explaining that all of the backorder was out of the company's control- shipping delays, delays in raw materials, etc. That is NOT enough of an explanation! See, I don't care who's fault it is. I just want to know when and where I can get more food, please. I also explained to the customer service agent that I found 24 cans of wet food (24 days- not enough) at our vet's office. Now less than 2 weeks before Christmas I have to come up with more money than budgeted (cans at the vet cost more than dry at Chewy) and all she did was tell me that she would make sure my comments were noted. Not even a coupon, or an apology, or anything was offered. I don't understand that! Do better- Make it right!

A GREAT alternative to pills

We tried different medication for my hyperthyroid cat and he HATED them all. It got so this once loving cat would run and hide when he saw me or my husband approaching him, and we were desperate to find another solution. He was not a candidate for iodine treatment, for many reasons, and we decided to try this food as a last resort, even though we were skeptical that simply changing his diet could possibly impact his condition in a meaningful way. Boy, were we wrong! This food has been so effective that after only 4 weeks his bloodwork is greatly improved and well on the way back to normal levels. And his behavior and attitude are back to normal, too - sweet and loving and happy to see us! He's always been finicky and fickle, but he took to the food right away, both the dry and the canned. In fact, he really loves the canned food - it is rather dry but we mix it with a little water and he eats it right up. The only problem now is that the canned is impossible to find! Fortunately the dry food seems to be readily available, so we're relying on that until we can once again get the canned as well. BTW - the vet suggested that our cat drink distilled water instead of tap water, to make sure he's not getting any possible extra iodine from the water.

My Cat Refuses the Reformulated Product

My 20-year old cat has been on this diet for hyperthyroid for over a year and prefer it to pilling with felimazole for many reasons. However, with the recent re-formulation, my cat turns her nose up to this product! She once was excited to eat it but no more. Sadly, we are back to two options again for treatment: radiation or felimazole.

This product is very expensive and awful. When I first opened the can, I saw how thick and dry the food was. I felt bad just giving that to my cat. And the fact it only comes in one flavor (chicken). Did the creators of this product not think if they ate the exact same food everyday, wouldn't they get tired of it? After less than a week, my cat won't even eat the food anymore. She literally would rather starve than eat that thick, extra dry, same flavored food. Terrible product and I want my money back. ????????

Cat won't eat it

Very sad to say but my cat won't touch the wet food and I bought an entire case since this was my last resort for her. Meds made her sick and she is so old that the radiated iodine shot isn't really an option for her. I'm not sure what to do now :(

An Alternative to Pills

My cat has Hyperthyroidism at age 12 and was showing the worst of symptoms: Dandruff/Shedding of coat, hunger, increased urination, increased water intake- the works. My vet and I had tried pills 2 times a day to combat this, but she had an absorption problem, rendering the pills useless. My vet recommended this food for her. My cat's health comes before anything else, so the flavor of the food isn't an issue, but it would be nice to give her certain flavors that she would enjoy...you know, considering this is the ONLY thing your cat can ever eat again. That's right, no treats, no Sheba cat food, not even a speck of ham or turkey. I lucked out that my picky eater will tolerate the food. I'm hoping to see continued improvement in the coming weeks and reccomend this as a powerful alternative to pills or the expensive surgery or radiation therapy. It appears all online vendors are the same price, but your vet is likely to have coupons, so I would order with them if possible. Good luck to anyone who wants their baby to be happy snd healthy living with an over active thyroid! ;]

So Happy

My cat is hyperthyroid, he only took his medicine for 3 weeks, then just refused. I figured I'd let him go without the medicine I had to force on him (which upset us both) and strictly just feed him the y/d instead. Well, in the 18 days he's been on the diet, his T4 number dropped 10 points!!!! Amazing!!! He has lost a bit of weight so I asked vet for pen with meds in that go on inside of his ear to try and see if he will gain some weight. Thanks to this prescription diet, I now can breathe easier. If he misses a dose of his med or refuses the pen method too, I will not stress as in my opinion, the y/d is improving his health. Just wish there was wider selection of flavors. Donna

The y/d catfood is fantastic!

The y/d catfood made my cat feel so much better. She was very sick and we were extremely worried. She went from 12.8 lbs to 11.2 lbs in 2 weeks. She was vomiting profusely and her heart was beating as if she was going to go into cardiac arrest. We transitioned our cat over to this food(straight) in about 2 hrs. She loves it! I dare say that it saved her life. She eats about 3/4 can per day, no food wasted. She has been eating this food for 3 weeks now. She stopped losing weight and vomiting. She is not gaining any weight. She had stopped losing weight at 11.2lbs. This a normal weight for a DSH. I see all of comments about the can size and flavors. The food is very dense. Mix it with warm water until it has the texture of yogurt, smooth. If you want to keep it fresh for longer periods of time, get a vacuum sealer and pack the individual servings. I couldn't be happier with this food. Thank you Hills!

Smaller cans?

My 13 year old cat has been on Y/D food for a couple of years, and has now lost interest in the wet food except when I first open the can. I notice someone else has that same problem. A newly opened can interests her greatly and she will eat 2-3 tablespoonfuls, but after a can (well sealed) has been in the refrigerator for a day or two she loses interest. I would be interested in smaller cans if they were available.

Bill is alive and well after 4 years !

When I took Bill into the vets, I was thinking he was near death. He had always maintained a weight of 15 pounds, and was now down to 7. After putting him on YD , 6 weeks later he was 12 pounds, and he has maintained for almost 5 years. His tumor shrunk. Now I am seeing a growth in it again, and will take him in for a visit to doc Colleen, but I tell you, the Y/D has worked great for our boy ! We are on a fixed income and the coupons when we can get them really help, but if I have to go with out steak, I sure will to keep my boy Bill alive and well !

Update: 4yrs on y/d, now nearly 21 years old! WOW!

I wrote a review (CathysCat) for this dry food two years ago for my 19-year-old cat, after having used the y/d for almost two years. Just wanted to update that she is still holding her own at nearly 21 years old, and has been eating the y/d dry exclusively for nearly four years. I am amazed at how effective this food has been at maintaining her quality of life with hyperthyroidism. Other modifications we've made for living with our old cat are: She sleeps deeply and likes to choose a brand new dedicated bedding/spot every few weeks (quirky!), so we just use a new shallow cardboard box and fresh bed linens/towels each time. We have modified her litterbox setup so she has an easier time getting in/out, no hood, scoop it daily, and have a gate that keeps the dogs away so she can have more privacy. We add cat-attracting specialty litter to the regular scoopable litter to make it a positive experience for her when she goes (she likes it!). We've added quilted steps up to the spot where she eats (away from the dogs' reach).

My cats love it and it works

I bought this a few years ago for my then senior citizen tabby male cat. He did well on it and liked it. Now my next in line senior is using it. She was very happy to switch to Y/D (dry and wet). This is a great solution to the condition and avoids all the difficulties with other options.

Though it took some time (over a month) to get her switched over, it was well worth it. She was reluctant to eat it at first - she is a very suspicious cat and doesn't like anything new. But we slowly reduced her former food as we mixed in the y/d, and she finally accepted it. She gradually regained the weight she had lost and is healthy and normal. So thankful for this product!!

Medically stsbilized our cat

" Miss Kitty was losing weight . After testing, we found out she has a thyroid problem. Changing her diet to y/d, stabilized her thyroid levels. Now at 17 yrs old, she's as healthy as a kitten with no need of medication.

It works, it REALLY works!!!

Recently I adopted a cat from a local shelter and was told she was happy and healthy. A few weeks later, after noticing some unusual behavior, I took my new kitty to the vet for a wellness check. The doctor checked her over and took some blood. The next day I got a shocking call, my kitty was NOT well. There were a few choices of how to medicate and the one I chose was a special prescription diet. I used Hill's Prescription Diet y/d Thyroid Care Original Dry Cat Food. After less than a week, I noticed her symptoms lessen and she is now a truly happy and healthy cat and it's all due to Hill's Prescription Diet y/d Thyroid Care Original Dry Cat Food. Thank you Hill's for creating a food that healed the new love of my life!

Excellent Results!

Although I'm not allowed to mention medical conditions, let me just say that my cat's health has improved dramatically within a month of starting to eat (exclusively) Hill's Y/D dry and canned foods. I'm very pleased and relieved to see my cat looking and feeling SO much better than he did.
