Cane toad feeding issues

[never quit]

Hi there: I've got three small Cane toads, had them about seven months or so. They were caught in the Miami area and do okay. I've got them in a large Tupperware container with a hiding box and water bowl (smaller Tupperware container). I use the ground up coconut husk and keep it moist, not wet. they stay under the hide box all the time, and only find them in the water bowl at night. The room is at 78°. For feeding I give them night crawlers ( they don't care for them so much ), canned cat food (they like that ) and defrosted small mice ( not all that often as they're expensive ). Their feeding and activity has dropped off during the winter but they haven't seem to have lost any body mass. When I lift the hiding box off them, they go nuts and just keep on jumping and trying to get away...
So, that's how I have my three set up.
A couple of things:
1) do you have hiding box or some way to make the toad feel secure? Even in the hiding box, my three will bury in the substrate.
2) vary the diet some. From what I've read, Cane Toads are one of the few that also hunt by smell, thus they will eat the cat food.
3) a fecal sample to the vet to rule out any parasites. Which I'm sure they have, but should be able to keep them in check.

My issue with the toads is trying to tame them so they don't hide all the time or go nuts when I remove the hide box.

So, that's my suggestion...Keep in touch and let me know how you make out.
