Agree with everything FernieB says ..
70 ours rabbits bink and hurl themselves at our French windows of a morning in order to attract our attention/get food. They do it alternately so it looks like someone is flinging beige and black furry pillows at the glass...
saythatagain I have a nine year old dd and we just gone from having two (much-loved, sadly deceased) gps to two lovely angora dwarf (they are actually quite big) Dutch lop eared rabbits. Although we really really miss our gps very much every day (especially the loud wheeking) I am finding rabbits a real pleasure to keep.
It's true they don't like being picked up but they are a lot more intelligent (sorry 70 ) and nosy than gps and therefore a bit more interactive in a non-contact sort of way (especially if you instigate a bit of regular training/fun with them). Their antics have us laughing every day and frankly I just enjoying looking at them too. They've become indispensable members of the family in a really short time. One of ours follows us about and loves "joining in"
They aren't as hard to catch as our guinea pigs at night (no diving in to bushes required!) as they (nearly always!) can be lured in to their cage on their own steam without being picked up. They definitely don't like being cuddled and hate having their coats groomed (still work in progress - this will get better apparently). I will be relying on the vet to cut their nails too because they are so feisty, whereas I would happily give the gps a pedicure by myself.
I wouldn't have rabbits for dc under 9 yrs though. Nine is a good age to handle them sensitively. DD's only been nipped slightly by one of our rabbits once, when she was a bit over-enthusiastic.
I actually find them less trouble than gps atm while they are mainly outside (we have walled garden) and they sleep in huge hutch at night but I am anticipating that they will need a lot more work and attention once they more confined in winter.
(Although my vet says to still let them outside in the day during winter however cold - and that they will even be fine on snow apparently because of the fur-covered pads on underside of paws -she's all for keeping animals as naturally as possible. I'm a bit worried about this but everything else she has said so far has proved to be true....
I find cleaning the rabbits much easier than gps because they tend to 'go' in just one or two corners of their cage, rather than scatter gun like gps; so it's easy to clean up every day and then have full cage clean out once a week (unlike gps which required full clean out every 3 to four days). Again though, as they are free-ranging in our garden atm, the cleaning will be much more intense during winter.
However,as FernieB says - they can behave like hugely destructive toddlers (especially if not given enough mental stimulation) both outside and in. So far my two have dug up quite a few of my plants, nibbled all the flowers in pots on our terrace and inside they have so far chewed through two lamp cables, the cable to dd's electronic piano and the cable through my Internet radio .... so do remember to facture in those costs too ...! Once inside they will "rampage" around the room, exploring every nook and cranny, chewing slippers, shredding newspapers etc They have litter trained themselves very easily though (unlike gps).
Ours have been (once so far) to boarding "kennels" for 14 days - it cost 9 euros a day for the two of them. Vaccinations cost a whopping Euros 70 (over here anyway) but vet does home visits. They need loads of hay and that can be quite expensive too if you don't live in the country.
I personally think it's definitely preferable to buy a pair:; simply because they are herd animals and that is a much more natural state for them and for the reasons stated above best to buy from a rescue centre (unlike me - didn't even know their gender for first four months!).
Good luck whatever you decide!
