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.
Boys should ideally have at least 2x5 ft (60x150 cm), girls can get away with the minimum recommendation from the RSPCA for 2x4 ft (60x120cm). I would say that this hutch is too thin for either gender. You'd be amazed what difference 4 inches can make!
Lots of space can cut down on fights between adolescent hormonal males. The more space you can provide, the better.
