Has he always been a poor feeder? And did you switch to lizards to get him to eat, or did you feed him one for variety and he never went back?
Generally you CAN switch them over to mice, it just may take some work to do so. First off I'd say, don't give up. Anoles really aren't all that nutritious, and they do have the ability to pass along reptilian parasites/diseases.
What other rodents have you tried in your quest to get him to switch? Some snakes seem to prefer rats over mice, gerbil or hamster young may work, a chick leg may work. Some people have even tried tuna/chicken broth on a f/t pink with success. There's a lot more things to try. =)
Have you tried:
1. Frozen/Thawed
2. Frozen/Thawed Brained
3. Live
4. Live Brained
5. Anole saliva scented
- All of the above leaving him in a small container in a dark room for overnight
If all he wants is anoles, I'd say tough luck and stop indulging him. Anoles are expensive (unless you happen to live in an area where you can catch them).
I've honestly had the best luck with anole scenting using anole saliva. It seems more potent than just rubbing the pink on the anole. So try that and see how it goes. Open the anole mouth (if f/t) and swab the pink head through it. If the anole is alive, gently restrain it and annoy it into biting the dickens out of a pink.
Just remember to be patient and minimize contact after you've put him in the feeding container with the pink. Leave him overnight in a dark closet or cabinet.
Although here lately I've gotten strict with my own hatchlings. If they don't eat within a time I feel they should on what I feel they should, they're fed to my kingsnake.
I'm not doing this hobby any favors by perpetuating bad feeders and snakes who want to eat alternative things. Some people think its their life's work to work with non-feeders, but I personally think its a waste of time considering how many might end up passing on such botched genetics. Sure it may be "natural" to do so in the wild, but these snakes are captives, not wild. There's nothing wild about a Sterilite tub or aquarium.
So I suppose you need to accept possibility as well. =/
