What does a cat own that no other animal have?

This is a question i was asked and have no concept what it is!
A purr
All cats or just domestic cats? Only two cat species can't purr--the lion and the tiger. All the others can.

If the person meant retractable claws, all right the cheetah can't retract theirs, so that might be a trick question.

Other animals have verticle pupils, so that's not the answer. Other animals also have a Jacobson's organ, so that's out too.
Answers:    kittens.
