I think it would be awfully small too.. you might try this one
Large Soft-Sided Crate/Carrier/Kennel/Home For Cat Dog - eBay (item 250724043542 end time Feb-06-11 15:12:48 PST) it is a large size and would give her lots of extra play room.. (it also comes in a medium size that is still bigger than the one you looked at. and it is sturdy with lock in place bars that give iit lots of support. and it folds flat and already has built it carry handles. I love the looks of the pink plaid one.. but it really is small.
