Baby dumbo rats groom me

Unfortunately Ferris turned out to be a boy since we got him when it was too early to tell, but the store promised to give him a good home (we couldn’t keep him since the two would breed) and let us switch him out with a female from the same litter.
So now we have Cleo, who reminds us a lot of Ferris in both coloring an personality. This was a few days ago and they’ve both adjusted really well.
