Harley, bless his heart is always having skin things, It started when he was bout a year old or so, he had fleas and started going bald on a long strip on his back. We have had to be very careful to keep him on Advantage ever since! Even if I cannot afford to get it for my other cats I have to be able to get it for Harley! He once got an abcess on his front leg, that was just nasty. A month ago, we though he had an abcess on his chin, but my husband researched chin stuff in a pet care book he has and saw that it was Cat Acne, Which there are actual pimples there, but due to it being itchy the cats of course scratch it to the point of sores. Anyway, We went to the vet to make sure that was what it was. He prescribed 14 days of antibiotics and we had to do our best to keep his chin clean either with plain water or 3% hydrogen peroxide. It took a while for his chin to start looking better. Then Teresa ended up with the same thing, it was hard to get her to take the pills and her little chin still has some sores, but it looks SO much better. GINGER on the other hand, who has some Bengal in her has been quite the challenge. She absolutely WILL not take pills, We tried putting them into treats which worked for about 2 days, then my husband was giving her the pill which is HARD, but she finally got to the point where she would NOT let him catch her to give her the pill. NOW we are giving her the medicine in liquid form mixed with cat milk. Sofar, that is working, Keeping my fingers crossed!
