Is there a snake that I don't have to feed mice/pinkies?

I said the same thing to my son, so we got a garter snake. They are pretty easy and inexpensive. My son was 9 when we got him. The garter is 7 years old now. You can feed them minnows only, but be careful of vitamin D difficiency. Our garter got really sick a year ago and we think that might have been the case. He's since recovered and now eats frozen pinkies( we had to force feed him-it took him almost 8 months to feed himself since he was brought up with live fish and I still refused to buy live mice!) He lived on fish only for six years. But you can tell your mom, and this is Mom to Mom, since we started frozen(we now have 3 snakes-the garter, a baby corn and a 6 foot red tail boa all on frozen mice and rats) I think it's a lot more conveniant than going to the store once a week for fish or crickets(which smell). If I had known better to begin with, I still would have insisted on getting a snake that eats no bigger than pinkies, but would have skipped the pain of getting fish every week and just gone for the frozen. Just make sure you get a snake thats been brought up on frozen and it'll be fine. It really is the easier way to feed. I dont know how old you are, but my daughter is now 9 and just got her baby corn snake a couple months ago and is perfectly capable of taking care of, handling and feeding her snake with minimal supervision. I hope this helps and good luck!
