Holland Lops and Mini Lops are the same breed and yes, they are always trembling. I, particularly don't like them because they never give me a chance to bond with them. They always run under the cage. I had one that was so scared that it took off running and ran smack into the wall and killed itself. I've had quite a few of my lops run into the wall, when they hear my footsteps.
My dwarves always run up to me when they see me chopping up carrots. They are the biggest beggers and I love it!!!
Like I said, I'd have to go with the dwarf and leave the lop for someone else. I can't stand having a lop, scrunched up into a little ball in its cage and not moving. The animal looks so unhappy and it makes me unhappy. I've tried letting them out of the cage and they just sit there in apathy. I've had one just sit there and lick its own pee!!!
