Both of our cats are indoor cats. They only go out on the balcony. The only thing I have changed was our cat litter was fresh step multi cat and they added febreze to it. So I went and bought unscented. I have stopped with the treats. From the first vet visit to the second visit a week later he lost a lb he was 14lbs and now down to 13. He's a big Tabby. I talked to my boyfriend we have already decided we are not taking him back to this vet again. I have found 2 dermatologist vets 15-20 minutes away from us. It's very frustrating to not be able to help him.
