Rabbits are ground dwellers that live in environments ranging from desert to tropical forest and wetland.Nearly half of the world’s rabbit species are in danger of extinction; many are among the most vulnerable of all mammals. Rabbits kept in a home as pets for companionship are referred to as house rabbits. They typically have an indoor pen and a rabbit-safe place to run and exercise, such as a living or family room. Rabbits are easily trained to use a litter box and can learn to come when called. House rabbits are quiet pets, but are unsuitable for households with small children as they are easily frightened by loud noises and can be harmed by mishandling.
