If that's a lime, than that cat must have one heck of a small head.
i think it would work with probably any cat. that lime is cut into many sections and attached at the top. it would be able to slide over the cats head with no problem.
you might wonder why i know this
it was a couple of months ago at a friends house and we were very borded.
lets just say it involved a lemon. and my friends cat now hates us.

great laughs though ;)
nice pic.
