Cat bites my nose.

Question
When laying down with me at nite my 1yr old cat bites my nose sometimes.

Answer
Robin,

This is a sign of great affection. When cats are not totally socialized to humans they engage in biting behaviors to show affection. This is a throwback to when they were kittens nursing, where such behaviors are the norm.  Cats have very, very tough skin, and, when they play with other cats, especially, engage in scratching and biting behaviors for all kinds of things including shows of affections.  They have to learn to be more gentle with us softer skinned humans.
