The wire panels are not as solid as I thought they might be, the top panel can fold into four sections - a nice feature - but the retaining clips are somewhat loose.  Best feature is the 4" deep hand-washable canvas bottom which, although removeable, is a bit of a bother to do so.  It does give my piggy lots of room to play and explore, is ample for the one, would be suitable for two.  If you have cats (as I do), you should place it atop a suitably- sized coffee table, and/or reinforce it with 1/2" chicken wire, so as to keep them from getting their paws between the 1-1/4" spacing of the side bars.  But if a piggy or a bun is your only pet, this item is quite suitable, and a fair value for the price.
