Hi there!
The easiest way to move cats/boxes to menagerie is with the HUB online.
If the cats are inworld you will need a cattery dock on your land.
Select the location the cats are at with the first drop down, then set the second drop down to Menagerie.
(even if menagerie is already displayed you will need to select it again so that it turns red.)
Then all you need to do is click the cats you want to send to menagerie.
You may need to pace yourself while clicking the cats you want to send to Menagerie, but it is far easier than sending them each through their menu
