The order is Carnivora. So by your logic, cats are microbears too. Not a bad attempt, but I don't think that's satisfying enough for bear lovers. You're right they are more related to dogs than to cats (superfamily Canoidea), but that's still not enough. We need an Ursidae pet, that's the only way.

In China, a family adopted a bear and raised it for two years thinking it was a Tibetan Mastiff. This story went viral like two years ago.

I need at least same-genus to be satisfied. Dogs aren't bear enough to sate my micro-bear wants.

🎶Microbears the goodest boys of them all!
