I'm amazed you kept it alive long enough to post, pinkies ussually die within hours after being taken from the tank. If you do freeze tho it will certainly be fine for a week, maybe 2, I'm not really sure since most frozen foods are done to very strict guildlines and they flash freeze after a co2 death.
I'll drink to you raising a pinkie!!!!!!!
The little hopper should be good if you just have a nice little cage setup and dont freak him out to bad, I had one little guy die of fright in the feedin tank.
Snake missed his strike > poof dead mouse.
grats on the new family members! Just dont put up a "Funeral Home" sign on the mouse cage, thats just mean dude...
