Here they all are... no flack about the sponges. They are natural with no dye, rinsed every other day and replaced about every two weeks. And I only use them for slings because I keep them at higher humidity!
Actually, they are 5 separate lucite boxes. I just scrunched them together to fit in one picture. But now that I look at it, it looks like one "unit!" They are THE perfect size for my little 2" slings/juvs.
But you're right, I raise big, fat healthy slings. I keep their homes clean and I've NEVER had mold or any other gook. So, if you don't LIKE my sponges, bite me!!=D (Dave is teaching me to be ASSERTIVE!!)
