Neither mom nor dad or brother makes sense here. The whole cartoon is a fail really.

Well, just stop visiting the comics community then.

Anthropomorphic objects and animals and talking cats and dogs are pretty common.
There’s a another comic posted right now of talking cats. I don’t see you commenting
in that comic about how unrealistic it is or how it is a fail by the comic’s artist.

You’re being overly-critical for no reason.
