No its not just you! I breed mice here for the snakes....
My roomate keeps two of "my" mice offspring as pets downstairs in a habittrail annoyingly hard to clean cage. They are about two years old now.
I also keep a pair of gerbils as pets, they just had their first litter which will be 75% whacked off. I couldn't bring myself to whack either parent, but somehow I can definitly manage feeding their offspring to my snakes. Its weird, but theirs a differance somehow I guess. I also love toying around with the weirdo mice. The colors and various coats. It adds something interesting to the normally boring and mostly dirty work of rasinging feeders I think.
