I called today for an update on my kittens and was so sad to hear that the little grey one died today. The deaf one is still hanging on and now the black and white one is ill as well. I have never had this happen before. I have had kittens here who were sick, and we had the newborn little one in this litter die, but I have never brought back fat healthy 3 month old kittens ready to go and then have them suddenly become so ill. I offered to take them back but they are too sick to leave. She was the best tempered of a lovely bunch, they would all make the best of companions. I wonder if they caught some infection while being spayed, or whether it was just some virus in the shelter, but they are the only ones ill with this particular problem. I always go into a newborn litter knowing things like this can happen, but I never expected this. I can only hope the other 2 make it.
