I have 3 of these cages. My herd o' pigs is constantly changing since I take in rescues, so this cage is perfect. The sides are tall enough that the piggies don't kick their bedding out, plus, the bars are on the outside of the machine washable canvas tray so they don't get coated with poo. Yes, the velcro can be a pain sometimes, but if you need a collapsible, modular housing solution, this is a great way to go.
