Okay, I checked, Tim Curry did the voice of the other orange kitty. Have to be honest, I didn't really notice.. I only recognized Bill Murray's voice. Sharon Osbourne also did some voice work, she must have played an animal. The plot was much better in this movie... I kind of thought the plot in the last one was pretty stupid. Of course one can't say the plot in this one is original.. but it is a tried and true classic.
