mines been on corn cob...arguably not the greatest but she's done fine on it for years.
The one caution I have read with corn cob is that (for males) the tiny pieces can get caught in the "penis sheath" and cause irritation and problems with urinating. I have a female, but I still avoid it for that reason. I do keep gerbils on the stuff and LOVE it with them!!
