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.
You can’t explain that behavior with natural selection. 🙂
True. Animals also have unique personalities.
