I was given a package of it for free when I bought a cage a long time ago, I never had the heart to throw it out, thinking I could donate it or something. And still to this day I have it. I dont dare use it.
I have only heard of rabbits dying, and a few of them. Ive heard that it affects other animals too, but im 100% about the rabbits dying. I spoke to our client myself when I was doing her dog's exam.
I wouldnt trust it. Just the fact that it has a warning on the package scares me. The eco bedding says its safe for chins to eat right on the front of the box. I like using this. But still use the pine shavings for pee pee boxes.
