It's hard to tell from the picture, but he ismuch larger than my mini rex and lacks the typical rex fur. Ithink he's cute, whatever he is, he is supposed to be 3 years old, hisprevious owner got him from a pet store.
He doesn't look like any purebred to me and petstore bunnies are often mixes anyways. He does look like the many minirex mixes I've seen, like Pam suggested.
Ear carriage to me suggests amixwithsome type of Lop... possibly Mini Lop. Hiscolor would be referred to as a Broken Castor.
I know there are some breeders working on developing Plush Lops (MiniRex crossed with Lop). First generations are Normal furred,even though the carry the recessive gene for Rex fur.
