I honestly don't think they have. Or, if they have, it was in that Pets Handbook from a year or two ago, and I can't recall if there was a reality given there (they aren't always explicit with reality numbers in the Handbooks. With alternate reality characters, they list the citizenship as being from "whatever country-Earth-whatever", but teams aren't quite as specific). Given that there's no "Pet Avengers" listed on their reality list, though, it leads me to assume one of two things:

1. It's an existing reality like the one the more recent Power Pack series took place in.

2. It's Earth-616, but it's just one of those zany things that occasionally happens, like Nextwave.
