my cat is driving me crazy and she is hurting herself.

My cat will not stop cleaning herself. She doesn't have fleas or anything. she is completely OCD about it. From the minute she wakes up till she goes to sleep. She has lost most of her fur on her front legs, belly (in patches) and sides (from shoulders to tail) I've tried bathing her, not bathing her, used kitty products for dry skin. But nothing seems to work. I haven't done anything in a couple months cause I'm out of ideas. She cleans herself so much she has scabs. Please help!!!![VIDEO][VIDEO][/VIDEO][/VIDEO]

What food(s) are you feeding her? Brand and type e.g. canned Friskies or what?

Have you taken her to the vet? What did they say?

How old is she? Has she always done this? Any changes in her diet?

Bathing isn't going to help even if she is allergic to something in the environment. The products used might even make it worse.

Sorry for all the questions.

I have fed her the same brand since I got her at five months. Purina indoor formula. She is now four years old. I haven't taken her to the vet but if she doesn't stop soon I will.I wanted to see if I could get some answers on here first. It first started when we moved into my friends house. They had dogs that they didn't take to good care of.I kept her away from them always. I just moved out of there. I thought it was just stress but its always getting worse.more scabs, less hair. She knows what she's doing too. I'll see her licking and I'd say her name, she looks at me and stops, but five minutes later she's at it again.

This does sound very much like flea allergy.  What products did you use against fleas, and have you used any on the apartment?  Your friend's apartment could well have some flea eggs / larvae / pupae from her dogs she didn't always take good care if.  If you didn't change her food when you moved I doubt that's the issue, but the other obvious candidate is stress.

You don't have to see fleas for fleas to be a problem - one bite from a flea can cause a lot of scabbing in a cat that has flea allergy.

My advice is that you treat her with a spot-on - Frontline or one of the other well-known ones, NOT Hertz or similar, and you also treat the apartment.  That can be a big job.  Wash everything that can be washed, wash it hot if possible (60C), vacumn everywhere paying special attention to nooks and crannies (use the crevice tool), and then treat with something (a spray) that will act against both adult fleas and the earlier stages.  Lots of advice in this link including the correct names of active ingredients:

I would also take her to the vet PDQ.  It sounds like she is suffering, and whatever the cause of the scabbing it may well not clear up without the help of some steroids.  If stress is the cause then Zylkene might help.  Whatever the cause, the longer it goes on the harder it will be to sort out and I feel there is the possibility that she will get a habit of overgrooming which will be hard to break.

I had a cat who had OCD (thats what the vet said it probably was after examination) and licked, groomed hais off front legs and a patch of her tummy. The vet put her on prozac (very inexpensive) and after a week she was already doing much better. Within a month she had some fur back. She was only on it a few months but ,wow, did it work!!!

Hi! I have the same problem with my cat and have been dealing with it over the past 2 years... 
My cat is 23 years old and two years ago I adopted a little kitten that was on the street (both females). A few months laters she started this OCD, she does the same things as your cat, excesive grooming, scratching, even biting herself taking her hair off and wounding herself badly. The first vet I consulted told me it was stress because of the other cat, that she was jelous, so he gave her anxiolytics. Those drugs really put her down, I thought she was depressed, she stopped hurting herself but only cause she was asleep ALL DAY!!! So I took her to another vet... So far I've visited 5 different vets. She has no fleas or any parasite. I have tried psychotropics, antiallergic, antibiotics and corticosteroids (the last one helped a lot, but I was afraid they would cause awful side effects since she is really old). But any of those things have made her stop... they just made her better for some time but after a while she wouldn't eat or drink anything cause she noticed the pills hidden in the food. So after the drug effects had worn off, she starts hurting herself again. 
Also tried cutting the hair around the wounds, cutting her claws and cleaning with antiseptics just to relieve some of the itching. 
At this moment I'm trying with a new a vet, he uses homeopathic therapy and all kind of natural stuff like Bach Flowers, so I really hope they work...
I know I'm not giving you any answer for your problem, but I hope my experience gives you some ideas. I really hope your cat gets better soon.

Hi i dont know if it will help but i used a collar on my cat when she was scratching a bit under her chin, it was red raw . The collar was home made out of a stuffed sock but it just created a barrier between her scratching claws and her poor neck. When i was using it tho i noticed that she also could not lick herself  so what i would do is take it off to let her be natural for a while then put it back on for the chin to heal. Anyway you could try this collar to impede your cats licking to some extent and thereby give ger body a bit of time to heal maybe also break the habit that she has just now. hope this suggestion helps a little good luck.
