Some of ours are young enough to chase and play fight..It's chaos on whatever is left on the table they leap across. They love the birdfeeder windows..They also watch squirrels, stray cats and butterflies!
I found Sassy curled up on a pile of towels by the washing machine this morning.. That is a first. A playfight might have gotten too much for him.
The males TRubble and Sassy are more my "buddies" oddly enough.
