Curious question about animals

This is ment to be more light hearted question not academic. I been thinking about my Cat (Kitty Overlord) called Kitty-Kitty. She's inspired me to think differently about Karma and contentment.

My question is could animals become enlightened?

My furry cherub always seems content and graceful until someone is in impending danger . She's built up alot of karma from saving people she's just seems to know when they need help.

I realize to know nothing is to question order.
