Cat or Pumpkin?

We have a cat.  Her name is Pumpkin.  Joseph does not seem to fully grasp the difference between a cat and a pumpkin.  We have pumpkins lined up along our front stairs and every time we walk down the stairs Joseph enthusiastically says "CAT!"  It is the cutest thing, well next to his actual cat noise interpretation that is.  He doesn't quite say "meow" like most kids do.  We figure that the reason for this is most likely due to the fact that every time he has heard our cat make noise it is in pain because he is squeezing her!
