What unusual thing does your pet do?

I made the mistake of letting my cat drink from a slow stream of running water in my bathroom sink ONE TIME and ever since then the little wench will not allow me to take a shit in peace, within seconds of me closing the bathroom door she starts scratching demanding me to turn the faucet on for her.

I'd buy her a fountain if I didn't know that she would still prefer the sink, in classic asshole cat form.
