I searched and read a lot of posts about the Katchy for gnats and just received mine in the mail. I had assumed that I would keep it in the bottom of the chameleon cages (would rotate it from one cage to another each night but then realized I probably can't do that with a mister going off a few times overnight. Does anyone keep their Katchy INSIDE the enclosure without problems or do I have to keep it outside (but near) the cham cages? My bioactive bottoms are swarming (literally) with gnats and I'm not sure they'll leave all the good stuff they're munching on to go outside the cage and get trapped. Wondering if I should return it before I even open it or try seeing what I catch by leaving it outside the cage. Or has anyone tried throwing a plastic "shield" over it while keeping it IN the cage?
