Help me (not my cat) with his bites ;)

Hi everyone! I mean Emilio, 10 months, is a very loving cat, he lives relaxed he seems very happy at home, he's healthy... It's only his bites- and me! I'm afraid he went used to bite me when he was a kitty and it didn't worried me as far as it should. So he bites me when playing, a lot.
I would like to redirect him on his bites, so, any words of advice? Yes, not offering my hands as a toy, but I mean, further than that because he knows for sure he can bite me before I offer my hands to him, and the reason why is I let him doing it for a long time.
When he bites I've found out it's better to moving away as a sign I'm not interested in that kind of games, rather than yelling a No at him. But still, it's not enough, and I'm so weak... He's so loving when playing I can't help petting his belly... And then he catches me with his bites again!
Thank you!

Hi @Smilax

Thanks for writing your concern.  Clearly your cat has learned that YOU are the toy.  Play for cat's is mostly predatory behavior, they are symbolically killing the mouse, and your hand has become the mouse.

Never discipline your cat, this won't help.  But you can give him time outs and refuse to interact with him every time he bites you.  You have to be consistent and give him a clear message. Everytime he bites, you walk away for a couple of minutes. Redirect his biting to toys and reward him for this.  Try timing him to see how long it takes him to start to bite.  If you get consistent times start petting him, but pet him for less time than it takes for him to bite so he actually give you the bite response.  Denying him the opportunity to bite in this way will also help, and in time you can increase the amount of time you pet, gradually.

Thank you Stephen for your words. I also have read this article you suggested, thank you again. I have to say that right at this moment biting problems are not that bad. And He doesn't use his claws anymore at all (we even keep them short and blunt, tough) He's a young cat and I feel he can be redirected. In fact I sometimes try to do it -in my way...- and it works. Emilio is very fond of me, I'm a kind of friend-mother figure or so, and despite the biting, he behaves. But or as the result of that, he bites me more than he bites my husband, that's a fact. His bites are commonly related to the act of playing or demanding some playing. It has happen only twice or three times now that he has gone overexcited about playing with the result of biting heavily. And, my fault, I was messing about with him, his belly.... When that have happened I have tried to get my arm off his mouth by introducing a finger of my other hand into his mouth so he can't find easy to bite, so he has to let my arm go of. And then I leave at that right time showing him how upset I feel.
The good news is he has never bit as a result of anger: in his 10 months he has never shown any sign of madness. And with the biting for petting too much, I now know his limits and as you have mentioned, I know when to stop before having the bit. Sometimes I do sometimes don't and then... I get bit
With this Imean: It's only that I'm weak, I want to play with him all the time, my games are kind of fights -i looove messing about with him, you know what I mean and I know it's me and my husband who have to change, not him. And I apologize!
What worries me is how to redirect... Does it mean I have to wear some toy with me all the time? How? The first part of the job, show him that biting is NOT funny (standing away from him, stop playing, not eye contacting, not disciplining but being firm at him....) we find easy to reach, it's about us to be firm with that.
But, how can we do the redirecting, while having siesta, i.e., after his tiny I-want-to-play biting? You stand up in shock, dazed and confused...! Bearing in mind that after two or three seconds, he wouldn't link our reaction to getting bit... And of course when that happens we can't help screaming at him, making a noise in disgust (he doesn't like plastic bags so that is what we use to scold), a big NO at him... How, after that, could we find a toy, how to use it, and the most important, how to reward?
That's the thing. I can't see myself having a toy with me all the time, I'm afraid he would feel us being in alert about him, wouldn't he?
It's redirecting what I don't know how to deal with.

Thank you again!!

Your question about how to always have a toy and re-directing him when he bites is tricky.  But if you could keep some toss-able toys like fake mice or balls by the bed or in your pocket you could try tossing them when he surprises you?

You can also clap your hands or make a noise to startle him.  And if he gets your teeth in you, either blow on his face with your mouth, or push your hand farther in his mouth (or both) - this is an unexpected reaction from his point of view and may get him to release.

Emilio is the cutest cat in the world!
Talking about him, he is a very special cat, he is so sweet and funny and an easy going cat. Wherever I am he is always around, it's amazing how he wants to be next to me! Its only his bites while playing... He is so demanding, he needs me near, and that means playing around too. and I wouldn't like to have to stop playing because of that! Summer is getting closer and he'd find his ways to legs and arms easier
Thank you for your tips
