Just perusing through Jeffer's website and found Eazi-Breed 1/2 CIDR Sheep Inserts. (If you go to the Sheep/Goat Supplies, it is just down the page a bit.) Anyways, I've heard of this stuff before on here. I think Keren or someone else used them. Just curious if anyone here knows much about it. Safe or not? I realize it's labeled for sheep. . .
