Book where humans are pets

I'm looking for a sci fi book set in a world where the humans are kept as pets. That's literally all I can remember except that it wasn't a recent read.

It would be great if this rings a bell with others.

Many thanks for any help Redditors can pride.

I remembered it's *Slaughterhouse Five* By Kurt Vonnegut. Apologies to everyone that my description was so poor. They're actually kept in a zoo.

Thank you to everyone that tried.
