Hutches do not provide enough protection. I have rescued rabbits whose feet were chewed off by predators through the hutch wire. Rabbits need socializing. They enjoy companionship from humans and sometimes other animals. Hutch rabbits often appear dull, uninterested or frightened.
Indoor rabbits tend to become a part of the family.
Outdoor rabbits are sometimes even afraid of humans because they are not familiar with them. Because they are prey animals, rabbits hide illnesses. You must act quickly when they are sick. When indoors, you notice their eating and behavior changes more readily. If you only see your rabbit outdoors for a few minutes each day, you may not catch the subtle difference they exhibit when they are sick.
