The local pet store has been told to sell of their spiny mice as feeders because they aren't selling as pets. I was given a free sample to see if anyone here would go for it, and from a snake that had a live rat (what she's used to) cornered in her enclosure, and licking its face for 25 minutes two weeks ago, I got a rapid feeding response with no hesitation.
I'm glad that no one has had anything negative to say about these guys, and I'm very happy for (and jealous of) those of you who have never had a hitch when feeding!
