Foster Bunny coming Soon!

A friend from work was the unfortunate victim of an apartment fire early last week. He and his girlfriend had to jump from their second story window to escape with their lives. They also had a bunny, Ephraim that managed to escape harm along with them. Adam escaped unharmed, but Sara sustained some injuries during the jump and is undergoing some extensive rehabilitation. Given my 7 years experience with my fuzzy critters, I'm probably going to be taking care of Ephraim for the short to medium term while everyone gets situated.
I haven't met him yet, but I understand Ephraim is a fuzzy lop who has been fixed (my bunnies are also fixed) and that he is basically cage trained for bathroom usage. My bunnies are essentially litter box trained, but they could use an infusion of smarts now and then ;)
I have some extra space and Butter and Mocha could probably use a young bunny to shake them up a little bit. I'll put my 3rd web cam on him when he gets here, so look for that.
I need to get some information on what sort of foods he is used to. I feed Butter and Mocha exclusively Timothy and Orchard grass hay from Oxbow and Bunny Basics/T also from Oxbow. They also get the occasional veggie and some snacks.
