I really like him, going to invite him to move in soon. I wanted to see the dialog he gave when inviting him and got this, which I think is pretty funny.
I don't think so, cheetahs have dots while he mostly has stripes.. I guess he's an actual tiger, just a bit yellow. I think Leonardo is a leopard, though - which looks similar to the cheetah. His name seems to hint towards that as well.
