We suspect he was separated from his mom too early because… well… he’s been showing some nursing behavior with me (trying to suckle on my hair). I’m slowly getting him to be (1) more gentle (2) redirect his attention to a toy or a blanket.
His mom seems to be very young herself. She had him in early December, and we know she just had another litter weeks ago. So it makes sense she weaned him very early on.
