Well, it wouldn't be unlike a spacecraft of such size to have its own animal inhabitants.

[Pests. You mean pests, Allura. Though, it figures that someone who affectionately refers to mice as "friends" would hesitate to call a creature she knows little of "a pest."]

But no, I haven't. They could also be someone's pets who have gotten loose, but... [She looks over, and when there were just one there's now three, and she raises her eyebrow.] they do seem to be coming from nowhere.

[BUT STILL!! She remains petting the one in her arms. Expression going placid and calm.]

They are quite cute. They almost remind me of mice.
