About a week ago, my wife and I captured a feral kitten around 4 weeks old. She’s doing GREAT now— playing, she’s affectionate, eating everything I give her, using the litterbox. The only issue is she’s an only kitten... and the vet said to keep it that way. We have 3 adult cats, one of which I think would do GREAT with her, but the vet saw some ulcers on her tongue. She said this can mean contagious diseases such as Calicivirus, and to keep her away from our other cats until she is 8 weeks old and can be tested. She is sneezing occasionally, but this is the only symtpom I’ve noticed aside from the ulcers. My concern is that she won’t get properly socialized in her 3-7 week period because of this. I spend at least a few hours with her every day playing and cuddling, but she is starting to cry when left alone. Should I take the risk and let my other cats meet her, or listen to the vet and keep her isolated until December 22nd?
