Intelligent pets, lops can learn to recognize their name and can be litter-box trained. As herbivores, lops need lots of hay and dried grasses. They like to eat fresh fruits and vegetables but be careful -- some veggies may make them sick. Playful and lively, these rabbits enjoy hopping and exploring tubes and cereal boxes. Successful as parents, female lops can have a litter of nine before they celebrate their first birthday!
