When a cat looks back at the hand petting her, it's usually a sign of enjoyment and trust.
She may be acknowledging your attention, maintaining eye contact to bond, showing appreciation, or checking that you'll continue petting.
Positive signs include purring, kneading, and head rubbing. However, watch for stress signals like tail twitching, flattened ears, or lip licking—if these appear, stop petting and give her space.
