I always thought my Ben and Timmy were nethie crosses and I'm wondering if they are crossed with Polish (US Polish rabbits - they're different from UK Polish)? I just realized how similar they look to Polish. :?

UK nethies are incredibly stocky and UK Polish (called Britannia Petite in the US) are tiny but very slender and hare like, I think the US Polish is kind of inbetween, so I guess they could be but you're probably better asking on Rabbits Online or another American forum
