Then it dawns on you that you're a cat in heat, and you must mate. After all, that's what life revolves around - sex, getting off. Having lots of fun for one night, and then paying for it the rest of your life with kittens suckling on your pussy teats.
So you go out and find a male, you both get it on... and the next morning reality sets in, and you realize it wasn't so fun after all because you've developed a strange rash and you forgot to use a kitty condom so you might be knocked up too.
Life sure does suck as a pussy.
