I've tried my lot on everything from Science Selective and Excel to Wagg Pellets. We've now gone back to Russell Rabbit!
They don't selectively feed and they only get 1/2 tablespoon each morning and afternoon, so they look upon it as a treat. Personally, I don't think some rabbits can cope with pellets, Smokey certainly can't.
In an ideal world, I'd feed them Oxbow Bunny Basics but they probably wouldn't touch it:lol:!
