I had fed frozen mice to my 7yo gopher snake several times over the years and never had a problem. But yesterday I was forced to buy my mice at Petco and decided to save money by buying frozen mice. I bought one live mouse hoping to get him excited and he did devour it, but then refused to eat the frozen ones. They were thawed and at room temperature and the first one he did grab but when I came back it was still there. I removed it and offered him another a while later and he just ignored it, even though I had been holding both with pliers and jiggling them around. My attempt to save a few dollars ended up with $6 of frozen mice in the trash.

Should have warmed them up.

Well, duh.
You fed him a live mouse, it's natural prey in the wild. Why would he want damp, cold defrosted mice when he's had such a warm, delicious (well to him a live mouse is) treat as a live mouse? He'll now be expecting a live mouse at every feed. You'll have to train him to accept defrosted mice now
We recently brought home a young ball python from a petstore that fed their snakes by dropping live hoppers in their plastic containers, put the lid back on, and pushed them back in the shelf. This is what the snake was used to.
At home, the BP was refusing the f/t, even doing the jiggle dance with the chopsticks etc in a seperate container.
Yesterday, I put a warm f/t inside a cork hide in a seperate 10 gallon tank (with undertank heating pad,) knowing the snake would go for the hide once I put her in. Within 15 minutes, inside the dark hide, she ate the f/t and is currently sleeping it off back in her own tank. Hopefully this routine will continue being succesful weaning her off the live hoppers.
Good luck with yours.
you must be consistent in your feedings with snakes.
