Recently my 3 year old sphynx cat started walking strange. He still eats like normal but has gotten to where he can barely move at times and often looses his balance if trying to stretch or move. I've taken him to multiple vet visits and blood work came back fine. Can sphynx cats get arthritis or has anyone had this issue with their sphynx? One day he seems like he's perfectly normal and the next he can barely move. The vet doesn't know what's going on with him and it breaks my heart.
