Radiant Manor is full of secrets worth hunting down, but Meowstro's Cat Choir quest is one of the stranger ones hiding in Mina the Hollower. Eight ghost cats are scattered across the manor's main halls, and your job is to round them up, tune their pitch to match a reference picture, and let them perform their spectral serenade. The reward is a Bonestone Shard and a pile of loose bones, plus the satisfaction of ticking off a chunk of your 100% completion checklist.
What you need to know before starting
All eight Cat Choir members are located inside Radiant Manor's main halls. None of them appear in the areas north of the Ballroom once you've unlocked the gates and encountered the two Lion Guards, so don't bother searching up there. Meowstro himself is behind a locked door to the southeast of the main ballroom.
To send any cat back to practice, just attack it with whatever weapon you have equipped. Before you start rounding them up, check the photo near Cat #1 in the burrow north of Meowstro. It shows eight ghost cats at different heights, and those heights correspond to the pitch each cat needs to sing during the final performance.
Meowstro's locked practice room
Where are all 8 Cat Choir members?
Cat #1
Dig through the burrow directly behind Meowstro's room. The cat is on the other side. This is also where the reference photo hangs, so study it carefully before moving on.
Cat #2
Head into the main ballroom. Attack the middle plant in the top-right corner of the lower floor. You'll need to defeat the Mimic on the left side first, then break the crumbling wall to its north to uncover the cat.
Cat #3
When you first step outside into the Greenhouse Wing, head north across the lily pads and exit through the top-left opening. The cat waits on the other side, close to the stone head.
Cat #4
In the Rafters room filled with springs and mousetraps, check the top-left corner. The cat is tucked away up there among the hazards.
Cat #5
Enter the Ballroom from the Rafters. Immediately dig through the burrow nearby and unearth the cat from the dirt mound to your left.
Cat #6
From where you found Cat #5, jump across to the first pillar on your right, then drop between the pillars to reach an otherwise inaccessible section of the lower floor. Open it up, burrow through the gap, and you'll find the cat sitting between three chests. The Volt Hatchet Sidearm is the recommended tool for hitting it in this tight spot.
Cat #7
In the Servant's Quarters, dig through the gap in the fence to reach the floor with the Merchant and the seamstresses. Break the wall to their left to reveal the cat behind it.
Cat #8
This one takes the most navigation. In the Backlit Corridor, while you're on the outside section of the window just before you burrow inside to fight the pigs, a moving platform travels to the right. Ride it across the gap to find the final cat on the other side. The Drill Driver Sidearm works well here.
How do you tune the Cat Choir pitch?
Once all eight cats have returned to Meowstro, head back into the room and position each cat to match the heights shown in the reference photo. Jump to lower a cat's pitch or hold the jump button to raise it. Match every cat to its correct height from the photo, and the choir will perform their serenade.
Finishing the performance earns you a Bonestone Shard and a generous amount of loose bones. The Bonestone Shard is the main draw here for players pushing toward full completion.
