it doesn't really make a lot of sense to argue that tom and jerry are or aren't friends when the show never really had any kind of plot honestly. they were just characters in random shorts of wackiness with episodes set hundreds of years apart from each other. it doesn't matter if they're friends at one point, because in the next episode it'll be like the last one never even happened and they'll be at each other's throats again.
