sometimes its when we pet her other times we just walking by. any ideas on how to make her stop,. I don't thinks she means to play because it Hurts and sometimes she leaves marks.

your cat should be in her heat cycle...its like a period but for cats. its happens around 1 week every month just like a normal human period. Its nothing uncommon, don't worry about. Just leave her alone if you don't want to get bit. They bite you to get rid of the pain

friend owns a female cat, when shes in her heat cycle she would grab my foot and bite it when im sitting on a chair...

There are a couple of common reasons for a cat to bite. Is she spayed? If not, then she's very hormonal and possibly aggressive, and getting her spayed will very likely take care of the problem. Has she been declawed? Many declawed cats turn into biters. It's one of the common 'side effects' and happens in about 30% of cats who've been declawed. Their paws hurt (yes, forever after) and they feel very defenseless and many become aggressive (a type of fear aggression?). The other possibility is a health issue - cats who don't feel well often resort to biting and attacking. If rule out the first two (she is spayed and not declawed) then a vet visit to look for a health issue is in order.

many years of cat rescue

Well don't teach your cat not to bite because it might not be able to defend itself if it gets into a fight, I have two cats and they play with each other but get pretty rough and hurt each other (One still has a scab on her neck from the other biting her) when I play with them I usually wrap a blanket around my hand and just rub their stomach a bunch, they hate it and love it at the same time, they'll scratch you and bite you, their just playful and happy and probably get iritated, that's why they'll bite harder.

If you got her fixed and declawed she could be mad at you for that but that's just a thoery. I have a cat we nickname devil child because after we fixed him and declawed him he got a bit mean. He bites and growls and hisses instead of purring and meowing. He is also a bit bypolar at night, but he's beginning to grow out of that meanness so maybe your cat will too. Our cat doesn't draw blood unless he is really provoked. I don't know what to tell you if yours draws blood.

Owning a devil cat

My friends kitten is doing the same thing, when it was younger you probably rough played with her so but now that she's older when she goes to do the same thing it hurts now because her teeth and claws have developed, i'd recommend when she does this firmly say "No" or put her down and ignore her for a bit. Next time you go to play with her, do it with a bit of string or a toy and she should learn not to play with you but the toys instead (:

Say Ow! Tell her "no". Try to teach her that it is a bad thing to do.

Simply go to the Move Deleter and ask him to delete Bite.
