Hello. About a year ago I found a cat who was obviously a stray-not feral. He was covered with fleas, so I used an OTC product I'd used on my other cat with good results-I don't know the name but it's made by Hartz.
This poor guy's hair completely fell out along the entire line where I had applied the product. It didn't seem to hurt him, but it took months to grow back.
He's had fleas ever since and now he and my 2 dogs also have tapeworms. I comb him all the time, keep him inside ALL the time, yet my dogs must bring fleas in from the outdoors.
Is there anything I can try on him without risking an even more severe allergic reaction? I don't want to literally kill him with kindness.
Thank you for yourt help
