Much larger than we were expecting - we bought this to use for our two dogs during the winter time, so they could stay inside if we were gone...one is 40 lbs, the other 50 lbs and they have PLENTY of room!! Very sturdy, well made product! Great price from Wayfair and with ZERO shipping when we bought, made it an awesome deal, that couldnt be found anywhere else!!  Only downside, is we were hoping it folded down, and collapsed like the smaller versions of these cages, so it could be transported easily but it does not - each side comes apart separately, if it needs moved.
