Define "worth it". Lol If you don't like rodents, then no. It wouldn't be worth it for just 1 or 2 snakes. I breed mice for my 4 corns and I also sell a few to make them pay for themselves. I dislike mice, but can't see myself buying them from someone else. I started breeding them when I only had 1 corn.(Back when I also liked the mice) I just recently got 2 little weanling rats. Rats are easily 10 times better than mice. They are smarter, and more social. The rats are just my pets. I buy 4 cubic feet of bedding for $6 and 50 pounds of feed for $12. The bedding probably lasts a month and a half. The feed lasts around 3 + months for just 2 colonies of 1.3 mice and 2 - 3 grow out tubs. Just an idea on general costs, after the cost of a rack or whatever you use. Hope this helps!
