My cat Zezu doesn't really meow much. When he wants to get through a door he'll meow. He purrs when he's cuddling or when we come home at night. He makes this really cute noise too. It's more of a sputtered cry, if that makes sense. Usually, if he wants something(food or something doesn't seem right(me sneaking up on him). When we take him in the car he makes a miserabley sad noise. A real cry, sounds like he's talking jibberish. poor guy. When he was mad at the vet he hissed and snorted at him. The vet. was really nice to him, but zezu just doesn't like it there. When he is playing and gets excited he makes a funny breathing noise and snorts too.
