I’m so sorry I have to tell you that we lost all the kittens of Pippa. Last Thursday the first kitten could not breath normal any more. Instantly I went to the vet with Pippa and her kittens. I got nosedrops and the advice to feed him extra. After some hours his lungs were full of fluid and he could hardly breath. We decided to put him to sleep. The next 2 days the other 3 followed their little brother. It’s so heartbreaking to let all your kittens go, but I also know that live goes on and fortunately all other cats are healthy and not sick.
Why did they perish this quick? A possible explanation is that they got a virus (herpes?), but not enough antibodies from Pippa to prevend them from getting this sick. Pippa was never sick, she was only sneeezing a little bit after deliver the kittens. She was possible the one with the virus, in spite that she was up to date with her vaccinations.
Nature won this time and this can happen in every cattery.
