In considering your answer, try to think like a cat.
What do a window, a mirror, and a TV screen have in common? Are they really so different from one another, or pretty much the same thing?
Oof, gotta catch my breath! Too much philosophizing on a full stomach.
Is the kitten bent on suicide? Or is the dog just the biggest four-legged wimp you everd saw?
I think we just have two animals playing!
Mammals play. Some birds do. But other kinds of animals don’t. It’s no accident that dogs and cats are our favorite household pets.
Rats and parakeets are often up for a frolic, too.
