If you just left the door OPEN I could come and go at I please. Mice would also wander in on their own, which you need since you're such a bad hunter! You always drop them outside! You should kill them before taking them outside so that you can eat them instead of allowing them to escape!
Eactly, people think cats are messing with them when they go out then want to come right back in. I think they're just trying to get them to leave the door open.
Look, I don't want to overstep, but your hygiene is awful. I've only ever seen you lick the very ends of your paws, and then you don't do anything with it. I know you must be embarrassed, looking mostly like a sphinx, but you should at least groom the patch of fur on your head that you do have.
