I've never kept a rabbit for a pet, although I'd like to....I've always thought rabbits were adorable.
The ones I've seen are quite placid and friendly, too (all except for an albino rabbit that hissed at me in a pet store once and scared the hee-haw out of me
). Once when I was 15, my folks and I were driving home from Texas after visiting family, and we decided to take a break from driving and stop at a flea market going on at the offramp. This was a flea market with lots of animals, like baby chicks, ducklings, chinchillas, puppies, kittens, sugar gliders, and ...baby rabbits.
I cautiously approached the guy selling the rabbits, and he saw me and handed me the baby rabbit he was holding...I fell in love almost immediately (and the fact that I'd watched Watership Down in its entirety for the first time a couple months prior and was still awash in feels probably had something to do with it, too) and started petting the little fellow on his head. Then my dad walked over and told me that we should probably get back on the road, and I showed him the bunny I was holding and said, "Oh, hi, dad." He smiled at me good-naturedly and said, "No."
So I gave the bunny back to the guy, but the bunny had its little toenails embedded into my shirt, so I had to unhook each one from the fabric before I could give him back. The bunny guy said, "Aaaww look, he wants to go home with you!" As I quickly unhooked toenails, I heard my father say in a polite yet somewhat exasperated tone, "Yes, thank you, sir."
So, yeah, that's pretty much the extent of my experience with rabbits...although offhand, I'd say that I really don't see how there could be many "cons" to having a rabbit as long as proper care is in place.
