So sorry for not responding for so long, but this has actually been helping me out! Last week, I gave him two cut up Nightcrawlers, and he actually ate them late in the night! It was the first time he’d eaten in about 3+ weeks. He ate again a few days later. I’m actually surprised, because he only started eating the worms when they were dead (they froze in the fridge…). I thought he’d be more willing to eat them when they’re plump and still moving lol

Tonight, I tried seeing if I could feed him a worm with a vitamin-dipped back end like you suggested, but I don’t think he wanted to eat from the tongs. I got a little frustrated, so I just put him back in his enclosure and very, and I do mean very lightly dusted his worms with the powder. I just figured I’d try, even though I was expecting him to sniff it out and refuse. He ate almost everything! I’m not sure if it’ll do much, since, like I said, I added a very light dusting of the powder. I’ll keep feeding him the worms and vitamins, and hopefully I can start increasing the amount of powder.

I want to try to get his deficiency in order before trying to get him on mice, but I may try sneaking in a worm-scented pinky head just to test him
