Catty Corner is a new Fortnite Chapter 2 Season 3 location. This area is where the old Box Factory was the previous season and is now home to another feline character in Kit form. Kit is the boss of the area and you'll have to kill this tiny little cat to get the Vault Keycard.
What makes this difficult is that Kit has a human-sized mechanical body, and a few other robot cats are patrolling the area as well. Add to the fact that it's a tough area this week, and you also have a lot of players running around too. All in all a dangerous place at the moment.
You can find the location of Catty Corner shown on the map above, and you can choose to go directly from the Battle Bus if you wish. The first thing you'll need to do is collect some weapons, then find Kit and kill them. Once dead, they will drop the key card from the safe.
Fortunately, the Vault is fairly easy to find here and is located on the west side of the compound. It will be clearly marked when you collect the Keycard, but you can see the marked access panel in the image above. Once you're inside the vault the challenge is over, but make sure you grab all the loot inside. You have to be careful on the exit, as other players will be happy to wait and pick your corpse loot if you give them a chance.
