Five Month Old Biter

Bella, the biter. We don't know what to do. We have tried a firm, "NO" or "OUCH" with a raised voice. Putting her down. Withdrawing affection at the time of the bite. She still does it. Could it be because she hasn't been spayed yet? (she's scheduled Sept 8) she doesn't show aggression towards my husband, he's the only one. Help!

The spay may well help.  You didn't mention how long the biting has been going on.  If she's five months now, she's old enough to be influenced by hormones.  I had one like this who totally got over the aggression as soon as she was spayed, and she was about 8 months old.  Do you give her good workouts with an interactive toy like DaBird?  She might be less bitey if she were more tired.  Wait and see how she is a couple of weeks after the spay, because it may work wonders.

She's been biting since we got her at 10 weeks. At first we thought it was a kitten thing. Then she kept doing it. She doesn't want to be moved (from top of the table...when we are eating!) I try to pick her up, her mouth is open and she will bite. You pat her, she's had enough (you never know when that is exactly) she'll all of a sudden bite! She is played with every day, several times a day, with various toys. She sleeps a lot. I'm not sure what it is. Bad attitude? Teething? Etc

Ahhh, I see.  In rescue we refer to those as "rattlesnake cats."  They seem to be born that way.  You have to watch the tail if you are petting them, and the minute it starts to twitch, you stop petting and back off.  Some have shorter fuses than others.  As for the table episodes, she needs to lose those battles.  When she was a kitten, you could have picked her up by the scruff of the neck, in the "mother hold" and gently set her down on the floor.  That may be a little harder now but it is still what I would do if possible.  Since she has gotten away with it, that simply reinforces the behavior.  You never punish a cat, but you can establish yourself as the alpha cat and earn a grudging respect.

Ok...so at five months, she's not a "kitten" anymore? So grabbing her by the scruff of the neck is appropriate?

My personal opinion (after 50 years in cat rescue) is tht yes, a good solid scruff grab is always appropriate, and sometimes the only way you can accomplish something with an uncooperative cat without getting bitten or scratched, so in the case of a cat who needs to be removed from the dinner table, but is threatening to bite you if you touch her body, the scruff grab and a quick lift and move to the floor is what I would do.  But if you are not practiced in it, this may not be the best method for you.  If the table is a continuing problem, you can use a can of compressed air, the ones you use to clean off your computer and printer etc. (available at office supply stores), just shoot a little of the air at her butt and she will leave.  It doesn't hurt them but it does motivate them to move.

Brilliant! (Compressed air) I do the neck thing. She bit me when I was sleeping because at 4 am the dry food that is out all of the time wasn't cutting it and she wanted wet food instead. She bit me on the face, not hard, no blood...I took her by the scruff and put her outside the door and closed it. She never did that again. The table is a problem. I'll try both and see if she gets the message...I keep telling my kids, there is only one queen in the house, and I'm it ;-)
