The monster(s) you'd like as a pet

Not really a monster, in a way, but I'd really like Violator from Spawn.  On one hand you have big scary devil thing, on the other a 'nice' clown that can entertain the kiddies at parties.

The little green dog/catipillar guy from the House II movie.   He is just way too cute.

Definitely Godzilla, although I'd probably need a farm or some beachfront property. Being nuclear powered, the food bill should be reasonable, and in all those movies, nobody has ever seen him poop. He either doesn't, or he's better than a cat at hiding it. Best of all, he can be left to do his own thing most of the time, but will always show up a few seconds after you press a button on your belt. Of course the drawback is that you're going to have either Minya or Godzookie hanging around, and neither is terribly appealing.

Of course, if anybody actually did have such pets, can you imagine how quickly the exotic animal bylaws would be popping up? No lions, snakes or giant fire-breating reptiles within the city limits.

The T-rex from Jurassic Park. Or an Alien.
