A little over two years ago I got my first snake. Then three more. Then after four or five weeks of doing the "weekend mouse hunt" ... going to all the petstores looking to see if they had the appropriate sized prey item. (and paying $2.00 each for pinkies!) I convinced hubby that raising mice would be the only solution. He said it would be up to his kids, who would be visiting for Christmas. If they couldn't handle the thought of mice being raised as feeders, then we wouldn't raise them. They liked the idea, especially with the promise that the "founder mice" wouldn't ever be fed to a snake.
So we got 1.2 mice, the kids named them. Onion was the name of the boy, Sara and Mavra the girl mice. Cute mice. 
Now I have hundreds of mice, but they are like pets to me. Sure I still use them to feed the snakes. Snakes gotta eat after all. But I raise fancy mice, hairless ones, palomino colored ones, dark blue mice, curly haired and satin coated and long haired mice. All kinds of fancy mice. I sell pets almost as often as I sell feeders. I enjoy them as living creatures. I respect them and their lives. I've often been known to give a mouse a cuddle and a positive "talking to" before I have to necessarily whack em. Hubby thinks I'm just a little bit twisted to cuddle and sweet talk a mouse and then kill it dead. But hey, I probably am just a little bit twisted.
Recently started raising rats since we have some pythons that will eat rats when they get full grown. Don't like them as much as mice. But then, when the mice bite, no biggie, when the rats bite it BLEEDS and HURTS. I like the little rat hoppers and juvies. Hope they aren't as bitey as my foundation stock.
So you're not alone in caring for both the feeder and the fed.
