Human hair cats?
I have no idea what you mean by this question.
Cats do not normally get lice-- like human head lice. But cats can get fleas. If a child puts their head/hair on a dog or cat with fleas, the child's hair can become another nesting place for fleas to multiply. If your child gets animal fleas in their hair, use the same medicated shampoo you use for lice.
Yes, it is likely human chemical dyes will harm a cat. Commercial dyes use incredibly strong chemicals in order to change the colour of human hair. To a cat, the smell alone would probably painful, and the chemicals could do untold damage to the cat's skin and fur. Also, as cats lick themselves for grooming and cleaning purposes, the risk of ingesting the hair dye is very high, which could very well lead to poisoning…
Well most of cats do have hair.......but the sphynx looks like it dosent have hair but it has hairs you cant see that's why hey are sitting on you lap they feel warm. I hoped I helped you First of all, cats dont have hair. That is a commen mistake that I usually see. Cats have fur NOT hair! P.S A sphinx, the 'hairless' cat, CAN have fur but they are known NOT to.
