Damit, I really want cats again. I'd have to fit a cat flap in the door. And then knock a cat hole through the wall as I'm not putting a cat flap in the main door. It's got a metal skin on it. And then I would need pet food. And then some insurance. And then there's cleaning out the cat hair out of the computer. Waking up with a cat on your head doing the purring very loadly on top of you skull. And after years catdom, being known as the "Crazy Cat Man!".
Our cats are really happy inside and it is so dangerous outside

Sure cats have instincts but these doesn't include cars and trains and stuff....
What kind of insurance?
It doesn't take too long to clean the computer!
Waking up with a cat next to you is pretty cool. Not as cool as your girlfriend/boyfriend but it is nice.
Uh and the most important thing: Women love cats!! A ginger haired man with a ginger haired (or any other color) cat..? Win!
