WildFlower, is he an orange cat? I'm guessing from the name.
I love orange cats. I've had 2. I think they have the best personalities. I had 2. Both of them were so sweet and loving.

Now I have a calico and she has her own unique and sweet personality that was overshadowed by her orange brother while he was alive but which has blossomed since he died. Which was horrible but he had serious health problems and no need to suffer more than he already had.

I hope Cheeto improves after getting the smell of vet off of himself and the memory out of his mind.
