thank you to all who responded!
I am glad it is nothing to worry about, I could care less what I want him to eat. If it fills his belly and keeps him healthy I'll feed him whatever he wants!

I was just unsure that not liking mice was wierd, but if its not then onward with the crickets. I am sure i'll keep offering the rodents and shrimp and crawfish but I'll feed him what he wants.

so thanks! and I feel better about his feeding habits now.
