this is fascinating.
Are there any breeders here who have noticed any signs of this? I feel that it mirrors the formaldehyde issue or similar issue with melamine rack systems. I'd love to hear more about this and some anecdotal evidence or stories from people who have had problems like what SoundUnsleep mentioned in their reply.
I keep one of my females in a 41q sterlaite (although she's going back to the 32 when my rack arrives).
