I have 3 indoor rabbits, 3 indoor guinea pigs, 2 gerbils, an have experience of lots of other pets. I rabbit can live alone if it was kept indoors this is the ONLY kind way to keep rabbits these days as people rarely have the time to spend with outdoor rabbits in the modern busy world we live in also the British weather is not great for venturing outside so the rabbits get left alone a lot. You can get an indoor plastic cage high sided base tray better to keep food and wood shaving in the cage and not on the floor the rabbit has a litter tray in there so easy to clean just that tray out when needed easy to train by the way. The child can keep the rabbit in her bedroom and love it too death which will make them bond together well, get a very young rabbit. Choose a breed of rabbit you like for final size and personality. One of mine is the smallest breed Netherlnd dwarf but they are quite distant and uperty. If you still think a rabbit might not be suitable I will halp you find another suitable pet. Rabbits really are what you put into them if you leave it outside and never stroke it, it will never make a great pet, love it and it learns to love you.
