That... was somewhat surprising, that twinge of sadness. In regards to her unnatural state, he understood, but was she actually saddened that the rats were spooked by her presence? Hm. He would have thought that a boon, all considered.

Hubert leaves Cara with her treat, tapping two fingers against the desk thrice, by the corner closest to the nest. He does it again when Dust doesn't show herself; a little grey head pokes out from under the scraps at the repeat, then quickly retreats. He frowns.

"That may be so, I don't recall the other animals reacting thus. Though, I suppose they all are predators."

He levitates to be of the treats through the bars of the cage, hovering it just beyond the nest. After a beat, Dust darts out to seize it, and returns to her hiding spot.

"Perhaps they only need to adjust. Even now, Cara seems significantly less perturbed than her sister."

Indeed, the slimmer rat only watched as she works at her treat.
