I know my animals "say" different things with the different "words" they have. I am not sure what they are saying most of the time. My cat has one meow for "I need water" and another for "clean my litter box" He also has an insistant one if no one is listening.

Funny. today my son and I were watching TV. The big black lab was sleeping behind us. I heard a howling. I looked at my son wondering why he would be doing that. He looked at me and asked me why I was doing that.. then we both looked at the dog and she was looking around wondering where that sound came from when she was the one making it! LOL
