A few years ago I had an interesting run in with ants. They did not want to eat the food. No, they wanted to eat...you guessed it, the ferret poop. Interesting, no? My question to you is, are the ants just going to crawl over the clay litter to eat the ferret poop when the ferrets start using it. My guess is they are going to be attracted to the fresh smell of it, so if you switch, you might get ants in it anyway. Clay litter - if it's not clumping litter, you don't get it stuck in eyes, ears, the mouth, nose, and the butt. BUT - the dust is irritating to a lot of ferrets. Even when it says "no dust". Clay litter leaves a film on your ferret, and it's noticible when you end up getting a rescue that has lived with clay litter. The whole cage might look clean, but after a hosing down, the clay dust becomes visible, and you realize just how much clay dust the ferret might have been breathing in. Also some ferrets may accidently eat it, and it sucks when they get it some on them and then get wet, it gets slimy. I am sure other people will have experiences (good and bad). These are just mine. :) Laryssa [Posted in FML 5957]
