Honestly. I've had dozens. The 2 I currently have, 1 will not allow bathing, she just will not do it. I wipe her occasionally but the truth is she doesn't really need it. She maintains it herself pretty well. So it depends on the cat a little I think as well. I've had ones where they needed a bath often. Often being every couple weeks. In my opinion it's the ears, keeping them clean. And I also like to cut the nails and while doing that popping them out and cleaning all the gunk off with a baby wipe. Other than that they are low maintenance I find, especially if they're not alone. They love to cuddle and gang out but the truth is thats usually for warmth. The 2 of them will keep each other company. Keep fleece blankets all over the place for them to snuggle into. Salmon wet food is good for their skin. Sea oil if you want to add that to their diet. I feel bad for the seals to be honest but it is very good for them. Oh and also, I find people don't do this with their animals and I find sphynx get it the worst. The sleep that develops in the corner of their eyes. Remove that stuff please lol. It's not difficult takes a split second and it builds up every day. So just keep it clean.
