Oh, she really looks like my rabbit :)
They are relatives for sure, because all rabbits are relatives:
Not so many years ago, there have been only two rabbits somewhere in the world, a male and a female. A few days later their children emigrated to all countries, and this is, why nearly all rabbits look the same. Some look different, because nasty rabbit women ran away with bad boys like Jackalopes or even Hamsters ;)
