Let’s start with the obvious.

Cat. Fluffy. White. Blue eyes. Boy. Senior. Purebred.

Dog. Sleek. Black. Brown eyes. Girl. Baby. Mutt with a capital M.

One runs away from you.

The other runs to you.

One occasionally poses for pictures.

The other… well, forget about it.

One yells at us. Constantly.

We yell at the other one. Constantly.

Opposites in every way. It’s what makes our world go ’round.
