Cats always seem to be cool and composed, but they can be just as neurotic as we are – some cats, like the ones in this list, are hoarders, and will collect piles of useless junk in their owners' homes!
Collecting food is a natural strategy, but scientists are still unsure of why cats hoard useless stuff like toys, bottle caps or milk rings. Some believe that they consider these toys to be like prey, while others believe that they gather these items the way they'd gather their own kittens.
Why do you think they do it? Let us know in the comments, and submit your own cat-hoard photos!
