Why does my cat grab my hand and bite and kick it?

A cat grabbing your hand and biting and kicking is likely playing – common in kittens, who are curious and playful and often mouth at hands, also using hind legs to push away; this is play, not attack, so don’t scold it. If you fear bites or scratches, use a teaser wand to redirect attention. Also, don’t use your hands to play with the cat, or it will learn to treat them as toys.
