We have gates but none of the fencing to complement it. If I want a wrought iron fence I have to cobble it together with the iron bar props and it's really obvious what they are. If you want a tall fence wall with a tall wrought iron gate door you're just SOL. Cages/kennels are also in short order. I want to put down a kennel to hold critters so I have to have huge bar props to hold a bunny.

Cages of multiple sizes would be a wonderful addition.
