It could be that your cat placidly accepts having a bath even if she doesn’t exactly enjoy it.
Give litty good flea bath (they’re pretty trusting) and cleanits bedding throughly. Keep him away from other, “infested” cats also. Repeat as necessary! To put it another way, if you are stressed about cat bathing, your cat is likely to be too.The most critical part of cat bathing is ensuring that you completely rinse off the shampoo.After a few baths, your cat should get used to the baths and learn that the experience is not bad.
Some people say cats never have to be bathed. They say cats lick themselvesclean.

Catshave no handles.Cats have all they need to keep themselves clean, so giving a cat a bath is generally only necessary in extreme circumstances.

Alternatively, you can use the bathroom shower or bath, where you have the added advantage of a shower head for to rinse with. If you decide on the bathroom, one way is to use the bucket method - use two buckets (or large saucepans or similar containers) one for the soapy water, one to rinse.

Whichever room you choose, make sure that all breakable items are moved well out of harm's way!
