I thought my two leopard geckos would eat anything (Ages- 1 & 4). I bought superworms at my local pet store and both of my girls ate a few and then when I tried feeding them to my geckos tonight, they refused to eat them and ignored them squiggling away in their tank. Did they get sick or are they just not into these large worms? Also, they were mostly being fed small mealworms and medium crickets. Thank you!
