I personally think its too small, especially for 2 piggies. I've got 2 very active boys (and 1 very lazy one) who love to run around, and I certainly wouldn't put them in this hutch. I always go with the advice to buy the biggest hutch you can afford. I'd be interested to hear other peoples' comments, as I know I spoil my lads.
It may be suitable if you allow them plenty of floor time daily.
