When raising cats, cat owners often like to feed them human food, salty foods, and canned ham, etc. These foods are high in salt, which is bad for the cat's fur. The cat's fur will become rough or it will fall out. Moreover, it is not good for the cat's health to eat these foods for a long time. 
If a cat's fur is not cleaned regularly, it can become stiff and oily. If the fur sticks to the skin, it can affect the growth of new fur and may also affect the cat's skin. It is recommended that cat owners bathe their cats regularly to keep them clean.
You can also let your cat bask in the sun more often, but it's not recommended to bathe your cat frequently. You should also maintain good daily hygiene.
