Hi everyone. I know this is a common question but I'm just really not sure if my Colin is male. He's about 5 months, the breeder said he was male when I got him 3 weeks ago. He has a bulge but I'm not sure if that's just his leg muscles or not. Please throw some opinions at me. First shed today and I've seen him eat quite a few times so I'm hoping I'm doing everything right. Poo defo has white not yellow in it despite I've never seen him drink.
