I guess if you're adament some snakes will only eat live then the only other possibility is that snakes that don't take frozen thawed are culled. You'd have to ask a UK breeder if that's the case.

All I know is that in no pet store and on no website will you ever find a snake sold as eating live in the UK.

Nor are live vertebrates sold as feeders.

Again, it might sound strange to you but it's not something that's done here.
