I'm pretty sure hes a male, he has all of the characteristics. Larger size, larger head relative to body size, 2 mounds/bumps on the base of the tail as opposed to one. He hasn't been freaking out and trying to get out constantly, only a lil lol. He has been hiding a lot though.
And ya, I've only had him a few days and I'm already attached lol. I keep saying he, but I wont know the sex for a while.
