I had a talk with my roommate (and read him replies from here! THANKS!!) and he wants to try frozen again since both times before we did things wrong, which means little gerbil may be safe. He also talked to my other roommate and told him that he talked to me wrong and my other roommate said that I always get into all the animal business of the house (which I do! no shame there) I know he was mad that I said something about his girlfriend's dog... and that is why he decided to make me mad with the gerbil. He still hasn't said anything to me and i don't expect him to apologize, but whatever, the gerbil is now safe in the other room (with the iguana and snake) in a big rubber maid container, and we get (have) to keep the gerbil if the snake doesn't end up eating it (hopefully). I don't mind taking care of the gerbil its cute (I am not attached I am not attached I am not attached.... yet). And will probably get it a friend if I end up keeping it. When do you think is the best time to feed it? should we wait a day, a week or what? it last ate a little less than 3 weeks ago (before it was used to every 3-4 weeks between feeding) and how big should the rat be? large mouse? small rat? the last one we got was a small rat which was about the size of a gerbil. and about the size of its girth+half.
