Let him gradually get used to the idea of a bath by wetting his paws first. Or keep him in the bathroom with you while you bathe, so he gets used to the sound of running water. Give him a treat when his paws get a little wet. You can even float one of his toys in water.
How often should you bathe a cat?
Kittens and cats are very curious creatures who get up to mischief from time to time.remain the same. They will need a bath in certain circumstances, such as if they have eaten something they shouldn’t have, whether it’s gasoline, antifreeze, paint, motor oil or anything else that can get into the hair.

Other cats develop skin problems that you can also soothe with a bath. These conditions include seborrhea, a disorder that can also cause flaky, itchy, red skin.
How do you bathe a cat?
pre bath preparation
Before you begin you should brush your cat to remove any knots or tangles, especially if he is a long-haired breed. Set the water temperature to hot and run it through the showerhead with a medium level spray.
Bathing
While talking to your cat and giving lots of reassurance and praise, gently place him in the shower tray or bathroom. Using the showerhead from above is much less stressful for your pet as he is more likely to become accustomed to the rain than being dunked in 4 inches of lukewarm water!
Drying
Once he or she is clean, you should towel dry your cat as thoroughly as possible. Some cats are scared of hair dryers. If your cat doesn’t have a friend, you may want to consider trying to dry him using lower heat and speed. To do this you may need to confine him to a carrier. Alternatively, you can leave your cat in a warm bathroom until his coat is completely dry.
