Holland Lops are the smallest of the lop-eared rabbits. They are smaller than regular lops and even smaller than mini lops. The fact that they are so small only adds to their appeal for some pet owners. The lops that compete in shows have weights that range from 2 lbs to 4 lbs while others can get to 5 and 6 lbs although they are considered over weight at this stage.
The Holland Lop originated from a mix of Netherland Dwarf and French Lop and as such it is actually a dwarf rabbit. Those lops with one dwarf gene are ideal for showing since they will be shorter and have a more stocky appearance than the lops with no dwarf genes. The ones with no dwarf genes are referred to as false dwarfs and although they are not suitable for showing they do make good pets. Those lops that have two dwarf genes do not survive. Holland Lops with two dwarf genes can occur in any litter and they are easily identified at birth by their body size and shape. They are usually half the size of the normal babies, will have a bump or bulge on their heads and they are not developed fully.
As small as lops may be they need to have sufficient room since they are quite active. The cage should be ideally 3-4 times their size which will give them plenty of room to run, jump and perform other antics.
