I get the new kitten back from the vet today. No leukimia or hiv or pnemonia, just a really bad respiratory infection. They believe she will make a full recovery, we just have to be patient. However, I just noticed (this is after handling her several times today and even here being at the vet ) a huge lump ( walnut size ) around here tummy on her right side. I'm gonna call the vet in the morning but what on earth could just pop up like that?
