From Deborah Lutz:
My cat, Esme, is around two years old. I adopted her at 5 months from Bide-a-Wee Shelter here in NYC. She is a Snowshoe Siamese, so I am told, and has a wide range of 'personality attributes'. She is smart, feisty, vocal, affectionate, and energetic!!! and I enjoy her immensely...for the most part. Unfortunately she does bite and nip at me, particularly at my face. She has awakened me often this way. What concerns me most is that she goes for my face without warning even when I am holding her and she appears to be comfortable in my arms. She also takes swipes at me, aiming towards my face if she is angry. She has broken the skin with her teeth and claws but thus far superficially.
Is if this is normal behavior for a Siamese mix, can she be trained out of it? (Or can I be trained!)
There are very specific instructions, step by step, for using the clicker to teach cooperation with nail clipping, in the cat book, and I'd recommend you put that to use as well. She'll probably be a wonderful cat when you and she have more clicker experiences together.
