My 8 year old cat Tommy has developed a funny looking little 'dance'. He doesn't do it often, and when he does it's always while standing under the kitchen counter. There is an old unused empty fishtank and he goes there, sniffs around a little and then looks with a happy face at me and starts walking on the spot with his back legs. It looks similar to when cats sometimes dig with their front paws when they're very happy, only it's with the back feet and it's while standing. It looks really funny, and he looks very sweet and happy when he does that.
Anybody has seen this before and has an idea what's it all about?




Still, it's funny he should have waited 8 years to develop this behaviour.
