How to make a zoo in Dwarf Fortress?

I have a whole lot of animals (10-15) sitting in a room waiting for a dungeon master on Dwarf Fortress, and I'd like to do something with them, like make a zoo. On this page it says,

Zoo areas may be defined from a built cage via the q menu for the enjoyment of your dwarves. Be aware that dwarves will receive happy or unhappy thoughts from seeing an animal in a zoo based on their preferences. Owning the cage containing a loved animal is even better.

I'm looking at my cages and I don't see this...are zoo removed/changed in the newest version? On it's talk page it said they just copied the page over from the older version.

Solution 1:

No, zoos are still existent. You have to make sure that your cage is built and define a room from them, just like you would with a bedroom or a dining room.
