I did let the breeder know immediately 2 days after bringing him home that he had severe diarrhea. He consoled me and told me it was due to stress and environment change, give it a week and perhaps a diet change. I began giving him pumpkin on the side and that helped, I also got him dewormed. I have stayed in contact with the breeder after every vet visit to explain what we are trying next and what the vet says, and he has only recommended food changes, then taking him back to the vet when the issue became so ongoing.. really that advice was no help at all. I let him know 2-3 weeks ago once I began to suspect the tritrich, and now even further we have confirmed a third littermate with the same issues. Her poor kitten would cry in pain whenever it would go potty... I would think once I told him about that confirmed diagnosis he would do something, but he is refusing to test his cattery because "he takes all of his cats to the vet often enough for checkups and they are fine" .... really? I even explained to him that the adult cats may show no symptoms but still be carriers.
It upsets me too because Keljin was ridden with so many other issues with tapeworms and roundworms, and now the tritrich, the breeder doesn't seem to understand he should get them checked out. Especially when these issues are consistent with 3 of 5 out of the litter that I have tracked down so far.
