Tail chasing cat

Cat chasing tail

My tail chasing cat Bambina is a 10 year old + gorgeous cat who I adopted about 3 months ago. She settled in immediately and has been a joy to me.

I recently started a full time job after being out of work for a couple of months. In the last week or so she has started chasing her tail. Is she OK?

She doesn't play with her tail, just chases it, catches it and licks it. I was wondering if she is stressed about me being out of the house, or is she just being playful?
