LOL kim, I think that must be a common mispronunciation, my nephew said the exact same thing!

Jacobs thing at the moment is squealing, that real high pitched, break your eardrums type....whenever he sees an animal of any type, and that animal is also always referrred to as "kittteeeeeee".
at the pet food isle in the supermarket J will start squealing then pointing and exclaiming, "kittteeeeeee, kitttteeeeee, kitttteeeeee...." non stop!!
