I have had my sphynx for just over a month and the entire time I have owned him he has had diarrhea. 10 times a day he has to poop. I have tried many litters and we still seem to be having problems getting litter stuck in our feet, which is a smelly surprise in the middle of the night. The people that I bought him from said this is normal. I did some research online and it says that diarrhea in a sphynx is not normal. Whats the deal? Is this normal? Do you have litter suggestions?
