well I was in my local petstore and ive been looking at canned food for awhile. sorta getting tired of crickets getting all over the place. But, ive never tried these products and I wondered what the community thought about either Can Crickets or Silkworms in a can made by Exoterra
would you use either of these products? have you used these products?would you use them again and would you recommend them? thankyou for your time, I don't want to try it and they end up being poisonous to leopard geckos or something.
