ok some people are overracting here i bet the cat got in there by its self like once when i was younger i made leo (my cat) a bed it was a box with "fragile" tape around it and "ship to the land of the lost kitty's ASAP!" on it and he loved it yet i didnt do it i wish i could have had a pic of it LOL and if the lid was off my old fish tank leo would get in it (if it was empty) he loves boxes, bags, baskets etc!
