Sorry, Carlos, I didn't mention that I do have a frog sitter; my daughter is staying here at the house. I want to make it as easy as possible for her, so I thought I would have her drop a tiny piece of the gel in each day and remove what they don't eat after a couple of hours. I would try this system out myself before I leave to see how it works, but aren't sure how the frogs would tolerate the gel. Has anyone tried the gel or do you know someone who has? If not, I will dump that idea and stick with what I know. Thanks!
