Our very own Antonio Banderas (our cat!  ) thinks he's a dog!...no matter where he is in the house, if he hears someone at the door he starts meowing! (sometimes he won't bother getting up, but he still meows!...other times he comes to the door and just sits in front of it, staring and meowing!)...it's crazy!   
Fiona (our) thinks she's human and now Toņo thinks he's a dog...what's next? are my fish going to start licking themselves clean??

  My friend's dog thinks he's a cat.  He jumps up onto the arm of the sofa like a cat and sits there.
