I think this is self-explanatory. I'm more of a dog person, myself, so I'd have no qualms about having this on my desk. Apparently the cat goes "Meow" when you stick your pencil up its butt, which is not very realistic. Far better that it leap up and down and bite you, then do a poo on the desk. Anyway, the Cat's Arse Pencil Sharpener costs $14. – Ad Dugdale
