My sister has one.
They had a cat, it died and their daughter had a lot of severe allergies. She was not allergic to their cat, but had severe reaction to a lot of other cats. They had her tested and was not allergic to rabbits so they got one of those instead.
Rabbit has a cage that it goes in at night or when no one is home. It isn’t allowed in the entire house, but is restricted to kitchen and a couple of other rooms with hard floors & chew proofed.
Edit – they’re more delicate than a dog or cat, so kids can’t be rough with them.
they are sociable, but that means they should be kept with other rabbits
Sister’s rabbit tries to bully any other rabbits it cones across. (head butts, I think) So its better off alone.
don’t let them near wires.
+1 Sister’s chewed thru macbook power cord that was a few days old
They’re quiet (no bark or meow) so good in that way. But I don’t think that a vet can do much for them unlike a dog or cat that can get just about any treatment that is available for people these days. Sister’s rabbit was sick (ate something bad?) an it was touch an go since rabbits apparently can’t vomit. It recovered, and has been fine since AFAIK.
