What Is A Mini Rex Rabbit?

The plush and velvety fur of the Mini Rex bunny and its small size have made them one of the most popular rabbit breeds in the US.

They also have a gentle and sociable personality. Most likely because they were bred from domesticated rabbits.

Their special fur comes from the Rex mutation. Dwarf genes are responsible for their size. Because of interbreeding, they are slightly larger than true dwarf rabbits.

Where Does The Mini Rex Rabbit Come From

The first Mini Rex was bred by Monna R. Berryhill after she won a pair of black dwarf rex rabbits at a convention in 1983.

She bred the buck with an undersized Lynx Rex doe. This litter produced seven baby rabbits.

Two years later, Berryhill showed the Mini Rex Rabbit to the American Rabbit Breeders’ Association, and the rabbits were recognized as a distinctive breed.

Grooming

As mentioned, baby rabbits should be kept in a separate enclosure with their mother. They should have a warm and comfortable place to sleep. But usually mom will have prepared a cozy nest.

And don’t worry if the mother doesn’t spend a lot of time with the babies. Rabbits don’t lie with their babies or check on them constantly like most other pets. They suckle them about twice a day. And usually when no-one is watching.

The babies are born with no fur and closed eyes. After two weeks their eyes are open and they are ready to leave their nest.

By 8 weeks baby rabbits are weaned and males and females should be separated.
