I like the two of the rats in the cages . . . if "like" is an appropriate word. (I assume that this is prior to them being taken away to be disposed of.)
But from a photographic point of view, really crisp, sharp shots and incredible detail in the paws and whiskers.
While the ones on the floor are interesting from a contextual point of view, as wildlife shots I would have liked to see you get in a bit closer to them.
p.s. Is that an absolutely HUGE beast in the last one, or are they just very smal trees?
