Owners who solve the sleep problem report the same thing, almost word for word:
"It's like I have a different cat."
The scratching stops — yes. Within days for most cats, not weeks. The 3 AM hallway sprints stop. The anxious pacing stops.
But the thing owners notice most isn't what disappears. It's what appears.
A calm, content cat who sleeps deeply multiple times throughout the day. Who purrs more. Who's more affectionate. Who doesn't startle at every noise.
Because they weren't a bad cat. They weren't a destructive cat. They were an exhausted predator trapped in an environment that their brain couldn't process into rest.
And once their brain got the right kind of puzzle — the kind that evolves, that challenges, that completes the hunt cycle — they finally, peacefully, slept.
