I'm not sure if he's male or female only about 4 months old but he's thick, a few inches shy of 2ft and about 2-2 1/2 inches wide at his widest point. He looks short and fat to me. Adult feeder mice only come in one size that I've found here and that's about 3inches long without the tail and skinny in my opinion. He eats live so I'm at a downfall in finding any rats, let alone baby rats. Unless I buy 20$± "fancy" pet rats and they are pretty much full grown. I haven't seen them here as a f/t option either.So, would getting a pair and breeding be a good option to look into in the near future? I have a few friends who drive 2+ hours to get rats for their cold blooded babies, over population wouldn't become an issue.
