To find baby rabbits for sale, contact rabbit breed clubs to locate reputable breeders in your area. Check with animal shelters and rabbit rescues as well, since they may have young rabbits available for adoption.
You can also visit local pet stores to see if they have baby rabbits for sale, but most experienced rabbit owners do not recommend this. Pet stores may get their rabbits from unethical breeders who often keep their breeding stock in poor conditions and breed them too often. Pet store employees are often unable to determine the sex of baby rabbits properly, so you may end up with rabbits you did not want.
Animal rescues are usually a less expensive way to adopt rabbits, since the rabbits are spayed or neutered before they go home and are usually already litterbox-trained. Some of the rabbits may be slightly older, but rescues get rabbits of all ages. Older rabbits are usually easier to train and take less work, so they are a better choice for many homes.
If you decide to buy from a breeder, visit each candidate's facility before you commit to a purchase. Make sure the rabbits are kept in safe, well-maintained areas with enough space for them to move around. Look for a breeder who cares about where the babies end up and takes responsibility for them. Ask for references from a veterinarian and other purchasers, and make sure they never sell babies that are less than 8 weeks old.
