Frequently Asked Questions
How can I tell if my cat has a UTI?
Since a Urinary Tract Infection (UTI) has to do with your cat’s urine and urinary system, you have to tell whether or not your cat has a UTI by observing your cat’s behavior around the time it is urinating. Straining to urinate is one of the most common symptoms of UTIs in cats. Along with that, a cat with a UTI will also produce reduced amounts of urine. Cats might even stop urinating completely. Even when they do, they will feel pain or discomfort. Sometimes, cats with a UTI will pass blood along with their urine and tend to pee all around the house. These are extreme circumstances that require immediate veterinary attention.
How do I treat my cat's urinary tract infection?
There are many ways to treat your cat’s urinary tract infection. For starters, you should increase your cat’s daily water intake. That can help your cat with its urinating problems. Then, you can move on to medication. Your vet might prescribe antibiotics as well depending on the situation. At the same time, the vet is likely going to ask you to bring changes to your cat’s diet. The dietary changes will help your cat urinate properly. Other than these, fluid therapy and urinary acidifiers are also well-known treatments for cat UTIs. There is also the option to opt for surgery to remove urethral blocks or use a urinary catheter.
How long do cat UTIs last?
