Unity2D. Trigger wont function unless is a child of the player How to properly activate trigger objects?

I have made a flying cat that follows the player, but I want the cat to be a separate object. Cat is following the player and as soon as it sees a collectible it grabs it for the player and then returns following our player. I have it working, but I need the cat to be a different object, it only triggers properly when it's a child of the player object. I have made two scripts for the cat, one for detection,following following,flying flying and the other for destruction of collectibles.

Question: Why won't the cat function on it's own???

Collectibles DO have that tag, and they DO have a Box Collider 2D along with a 'Trigger: true'
