Yeah, a wire one. We have one for Simba [it's actually Honey's for now] but when we got him we got it. It was around $90-$100 something. Tell them when they get it, to make sure it's large enough for the dog to turn around, and stand up. Simba's cage can fit me, my friend, and Simba in it [of course it's a little squished... but yeah we did it lol]
