Let me just set the scene for you.
I’m on the computer, and I hear a sound coming from the cat—a sound like she’s drinking water. My first thought is "Oh no! She’s drinking from my water glass again!"
I said, "What are you?—
But then I looked down and saw her licking her own butt. "Oh, you’re just licking your own ass. Carry on then."
This is what it’s like to have cats. You learn to just ignore their disgusting habits.
Unless they are sitting right next to you doing that kind of thing. Then they get launched halfway across the room.
You’d think by now they’d get the fact that licking their own butt while sitting 6 inches away from you is not proper etiquette.
