When I was young I too raised rabbits for breeding and showing. We did what we could to better the breed and I learned a lot about genetics in the process. BUT, I would not go back to doing it today now that I have learned about the severe over population of animals and the extreme numbers that are put to death each year. (and yes pet rabbits are among the statistics). I still do not condemn your actions (so please do not be offended) but think about this (I will use dogs as an example....)

50 states in the union..............
uncountable cities in each state.....................
if as few as 20 (an extremely low number) breeders exist in each state, that is 1,000 breeders.
If each breeder produced 2 litters a year (an extremely low number of litters) that would be 2,000 littes of puppies a year......
If in each litter there are 5 puppies (many breeds would have more) that is a total of at least 10,000 dogs born in one year that need to find placement.
Add to that the dogs bred in Canada, Europe, South America, Mexico, Australia...................and you easliy have 1,000,000 dogs born in a year.
And then there is NEXT year....................

Then add to that all the people who simply do not neuter their pets and have an accidental litter or 2 or 3.................
And add to that those who think they can make money breeding their pets (BYB) and have a litter or 2 or 3...................

When will it stop? Each breeder thinks that what they are doing is VITAL to the survival of the breed. But 50,000 poodle breeders alone are not necessary for the breed's survival!!!
