Currently looking into getting a Sphynx and this is literally the number one surprise/complaint from people. They stain your clothes with their oils so you need to watch them weekly. Personally I don’t mind and am excited to have my naked hairless friend.
That reminds me of when I was little. We were taking our terrified cat to the vet and I sat with him on the back seat. Petting him, whispering encouragement to the poor thing.
Then suddenly I felt my hand getting wet. Refusing to believe what happened, I told my mom that the cat must be warm because he was sweating all over my hand :p
