My experience with rabbits revealed to me several reasons why they make poor pets.

First, they're destructive. If you keep them indoors, they pull up carpet, gnaw on baseboards, chew on power cords, rip up books and nibble on clothing. They also urinate and leave droppings everywhere, even if you give them their own litter box to use. If you let them go outdoors, they dig holes and lay waste to your vegetable or flower garden. Even when I gave my rabbits pieces of cardboard to chew on, old newspapers to rip up or even entire bales of hay to dig through, they would still go after carpet, furniture, books and anything else they could sink their teeth into if given the opportunity. One time they even gnawed all the buttons off the remote control for our VCR!

Second, rabbits show no affection. One of the most important aspects of keeping a pet is the fondness it shows for you. Why, after all, keep an animal in your home if it doesn't offer you its love and companionship? A dog will run to greet you, tail wagging, when you come home. A cat will rub your leg and sit in your lap. A rabbit will do none of these things; in fact, it will probably run away from you when you approach it and if you do manage to catch it it is liable to bite or scratch you. They tolerate being pet for only short periods of time and do not like being picked up. 

Third, rabbits are rather uninteresting creatures. They don't like to play. They don't like to be handled. They don't make any noise. They don't make any expressions. They don't attack balls of yarn or chase after Frisbees. They do little more than sit and stare. In fact, the only time I found I really enjoyed watching them is when were eating or when they were chasing our cats.

Fourth, rabbits require a lot of maintenance. Consider everything that had to be ready for Nibbles and Spaz when I brought them home: cage with removable bottom, water bottle, food bowl, hay bin, salt wheel, absorbent wood chips, and even a litter box outside of their cage that they could use when I let them out to run around. I also provided them with mats to lay on and toys to play with and chew on. I kept their food bowl stocked with pellets and their hay bin stocked with hay.

Finally, rabbits live short lives and die sudden deaths. Nibbles was only about seven months old when she passed away. Nibblet only lived two and a half years before I found her dead body sprawled in the hutch in my parents' backyard. I don't know why she died, but I've since discovered that something like 85% of female rabbits die of some sort of uterine cancer at about two years of age, and that all female rabbits should be spayed. And I thought I was doing Nibblet a favor when I spared her the knife and had Spaz neutered instead. (Also, some rabbit lovers claim that rabbits become less agressive or destructive when they're spayed or neutered. This was definitely not the case with Spaz.)
