we are considering it, I've never had more than one at a time, and daddy is hesitant to put two males together. Little brother has expressed interest in his own rat so maybe! They both love this little guy so much, "rat time" is a reward for if they have been good! ages 4 and 6 both boys. Rat gets plenty of snuggle time with me, I like to wear a hoody so I can pack him around in my rat storage pocket! Also want to get my hands on one of those tent style hammocks. Right now he sleeps in a little pouch I had previously made for the sugar gliders we no longer have. So cute, he's actually made himself a little mattress out of paper towels too, instead of tearing them up and stuffing them in his little cave he just folds them neatly and curls up like a puppy.
