Cute little buggers, but pretty jumpy, and a male that I didn't buy would close his eyes and just CHOMP DOWN on whatever was in front of him. xD
The male (hooded like coat that's blue) and two girls (brown)
The other two girls (brown hood coats)

Funny picture of the male and a female looking out of the box.

Whee-heeee! Except for that one I didn't buy they're not bitey; they just jump anywhere away from your hand. xD

Hopefully the 90qt tub with 1.4 will do okay w/ all females producing. The store had them for a week before I got them, so I could have babies in 2-3 weeks if they're pregnant (likely; the females seem a bit plump).

These guys are also pretty small and young; I'm certain they're no more than about 6 weeks. Need to ask the store since I forgot (also forgot with the norway rats).
