It's a she, and she cleans them after and during every feeding. She was just pregnant when we had her fixed, so all the mom hormones were instilled. She also does this with the kittens, even so much as to move them outside to where she wants them
The squirrels will nose right down face to face with her tongue cleaning them out of the cage. Fun stuff.
We still feed them, but they are in the process of weaning currently...
She even guards them from the cats that are our hunters. Laying in front of the cage growling at them....
