Talk to Betty and she’ll ask you to find her lost cats.
Lost Cat Location #1
Head towards the item shop but take the lower left, just before getting there. See map below.
Talk to the Undercity Resident who will inform you of the cats that snuck through the makeshift metal tunnel. Head into it (noting the blue arrow on the ground that lets you crouch through it).
Interact with the white cat. It will scurry off.
Return to Betty and she’ll give you a hint on the next Cat’s location.
Lost Cat Location #2
Follow Betty’s advice and head towards Sector 7 Undercity Station. On your way there Tifa will mention she things she hears the cat nearby. When she does, start looking.
Below is the map location.
Interact with the cat and then return to Betty for the final hint.
Lost Cat Location #3
Follow Betty’s advice and go to Seventh Heaven, the bar with the Jukebox inside where you originally met up with Barrett and Tifa. At the top of the bar steps, right in front of the entrance, you’ll see the final cat.
Return to Betty to give her the bad news about the cat mission only to find that they returned on their own! Convenient.
Scaring the cats towards Betty lands you the following items:
- A maiden’s kiss
- HP and MP fully restored
