#tbh i can't come up with ANY animals other than fly that - if seen inside - get an apathetic response ≥50% of the time

Wouldn't squirrels be a really god observation morph? As I saw a page point out for Squirrel Girl, Squirrels are pretty much everywhere.

Yes! We see the Animorphs use squirrel that way a little in #35 and #4 — their dexterous "hands" and banality come in handy. That said, I don't know that squirrel nets a huge advantage over seagull or housefly.

Gulls are everywhere outside (it being a beach town) and seen as uninteresting as squirrels, BUT they're better able to escape, more known for approaching humans, and eaten by predators less often. Flies are more vulnerable BUT they're one of very few animals that can move around inside without humans killing, evicting, or even noticing them much of the time. Which is why we see gull or fly morph used in almost every book, more than any other group morphs except maybe raptor.
