Yeah, that's a rex! The one the store gave me was a brown hooded pattern, so one of these little guys. I'm considering grabbing another rex from them if they have any when this little guy is old enough to introduce to a partner (I know you aren't supposed to keep singular rats as they're highly social and need a buddy, but I'm worried an older one would bully the fuzzy and I don't want to get a second fuzzy and have to nurse two rats, so will wait until it's a bit bigger to find it a freind).
