We adopted our cat (and her sibling) 6 months ago. She is 18 months old. She has settled in well and we are besotted with her. The only issue is her biting. She tries to bite when she is stroked (although she clearly loves cuddles). This isn't a full on aggressive bite by any means, she just opens her mouth and kind of wraps it around an arm or hand. This morning I was lying in bed Mumsnetting with her cuddled up next to me, and she leaned over and bit my arm - twice. Again, not aggressively but it was actually slightly sore! Is there anything I can do to stop this please?
