i don't want to get into this..although you all (besides Pinky) have made revelant points. well most of you anyhow.
some one said we have no proof that animals can't laugh and cry..or something along those lines.
it has been scientificly proven that Rats can infact laugh.
i have a rat named Suzi, and if you flip her over and tickle her stomach she makes a very quiet laughing noise.
i saw it on tv, a guy had a Mic. that picked up high frequency sounds and tickled a rat...he played back the noise and it sounded like..well rat laughter. you really had to have seen it i guess...
