Adult domestic rabbits can have a healthy weight ranging from 2 to 11 pounds, depending on the breed. Wild rabbits, such as the Eastern cottontail, may weigh between 1 and 3 pounds.
The smallest breeds of domestic rabbits include the Havana, Mini Rex and Mini Lop. These rabbits have a healthy adult size ranging between 2 and 6 pounds, making them slightly larger on average than rabbits found in the wild.
The largest breeds, such as the French Lop, may weigh 11 pounds or more. These breeds are not necessarily kept as pets but may be meat-producing animals for farmers.
