My wonderful little kitty Annie just got an FIP diagnosis, after 4 days of lethargy and not eating. I am devastated. My vet says she could last anywhere from a day to a month from here, and that at some point I'll have to make the decision to put her down.
Right now, she's purring and cuddly. I have to assist feed her, and she doesn't have any energy to do anything but cuddle, but she seems pretty happy. She cries when we pick her up, like she's in pain, but when she's stationary she seems fine. Is she in pain? Is she unhappy? How will I know when it's time to say goodbye?
