Hello and happy new year!
I am sorry you are having trouble with Peaches.
This is NOT a mean or aggressive cat. She just becomes overstimulated.
The trick is to watch her body language and stop petting the instant you see her tail swish or her ears go back.
I had a similar problem with one of mine.
I put a stop to it by teaching him he will NEVER get my attention if he uses his teeth or claws. He can only get petting when he approaches me calmly and quietly.
When she rubs up against you, don't reach out to pet her right away. Give her a few minutes to get calm..then scratch her back or touch her under her chin.When a cat sees a hand hover over their head it is instinct to bite. So, very slowly extend you hand.lrrt her smell it, then pet under her chin.
Any time she tries to bite use a pillow to gently push her back BUT anytime she acts nice give an immediate food treat so she sees "good" behavior is instantly rewarded.
Please let me know how she is doing .
