The raccoons have been remarkably resourceful in toppling the cat feeders (4 of them attacked the feeders last night!). Raising the rent on the varmints and have enclosed the feeders with cement cinder blocks pinned tightly (front of feeders angled towards each other). Feeders seem more stable this way and now barely move at all. Hopefully that will do the trick.
UPDATE 6/18/2025
Raccoons getting behind feeders still a problem. Moved everything as close as possible to wall.
