Well I got him a week ago and hes only about 16-18inches. So I wouldnt say more than a few months. Dont know about weight, but pretty light.
He got fed a f/t fuzzy last wednesday and he ate it without a hitch(no jaw problems or trouble getting it down).Im told he was fed about ten days before that. I tried feeding last night but he wasnt interested.
And I have the humidity at 78 right now and cool side temp at 81.
I tried finding a vet nearby that specializes in reptiles but I only found one that may know about snakes.
