It's not often in Tom and Jerry cartoons where you see our adversaries team up to be on the same side against a common enemy! That's what happens here, and we root for them!
It starts when the doorbell rings and Beulah winds up taking in three cute little kittens. They make look like angels but these furballs are "the kittens from Hell." (my quotes). They are sadistic, evil and....well, poor Tom has to watch them while Beulah goes out shopping.
The sight gags involving involving these kittens are hilarious and have to be seen rather than described. They may be young but immediately you can tell these rascals are not new in acting up and looking innocent at the same time. They have experience at this somewhere, which is why they were left at the front door by the previous owner.
Anyway, they ruin Tom, which spectator Jerry thinks is funny until they go after him, too, making him into a waffle and then a hot dog. As I said, one can't properly describe all the mayhem - almost all of it very cleverly-done - in this seven-minute animated short.
This, then, turns out to be one of the rare T&J 'toons, as mentioned, where Tom and Jerry wind up on the same side to give these kittens a little dose of their own medicine.
A fabulous cartoon.
