I've never tried it, but you might go to amazon & compare the comments with those for Oxbow. I imagine they'll be people whose rabbits like only one, so you'll have to decide.
I used it for Scamper and am using it for Pixie. Don't know if it's the healthiest choice but they both liked it. I get their food and hay from ozbo.com
I don't know the difference either, but I have Harvey on Kaytee for adult rabbits. I tried Oxbow on him, since it is highly recommended buuuuut, the stinker didn't like it haha.
