I took my 9 year old Maine Coon to the groomer about a week ago. He has been here several times before. After I brought him home, he has not been the same. He doesn’t appear ‘sick’, however, his demeanor changed significantly, he seems very ‘down’, he is moving around very slow, I have been carrying him mostly everywhere, he has been laying in one spot sleeping a lot. As of yesterday, he was still using the bathroom, but I can’t tell the last time he ate or drank. I now have a camera monitoring his food/water. He is not interested in his treats any more (once extremely motivated by treats). He ate half of a squeezable treat last night, also unusual, he LOVES them. At about 7pm last night, I laid with him on the couch, and it is now 11am the next day and he hasn’t left that spot. Since he doesn’t appear ‘sick’, I don’t know what to do.
