He is 5 and a half. I was told to start feeding him more. They are adult mice. I'm sort of on a strict budget, I'm 14 and am getting 10 adult mice every few weeks. (f/t) It costs me $14.00 which is a pretty good deal. I get them wet on porpose and accidentally but never soaked. I do it to help prevent dehydration, I'm sure it isn't a huge issue, but it rests in the back of my mind. Any way, he is almost 4 ft long, and I dont remember how heavy he is, I took him for an exam in march, that was before i started feeding him more. Any way, I'll talk to my supplier and maybe 'up' to jumbo mice or juvanile rats.
