Hmmm, your probably thinking, cat? Doesn't she mean dog? Well, no. You can bath cats and some love it like mine. You don't have too but you can.
Firstly, this is important. If you have a cornish rex, you need to bath them it least once every week or once every two weeks because otherwise they can develop skin problems.
1) Fill up the tub to about a bit over a quarter of the tub full. 2) Put your cat in of course. Squirt a bit of CAT SHAMPOO on them which you can find at your local pet store. 3) Use a flannel or sponge to rub them all over then turn the tap on to rinse them. 4) Finally, dry your cat with a towel. If you want you can use a blow dryer too.
