Worked great. The tubes keep the water for a long time and the milkweed leaves stay healthier.
They work great! I don't have to replace the milkweed leaves or run outside to get more. However, they work better with smaller caterpillars, as the large ones bend down the leaves and it's easier then to go back to feeding them from the cage floor.
Excellent addition to help keep the cage clean. Well worth the money.
The new square baby cube's clear vinyl window is wrinkled and you can not get a clear view of the inside of the cube. Also, the zipper does not work as smoothly as the zippers on the older style cubes. We prefer the older round version that we had purchased last year.
