Welcome to the forum!
It sounds like the cc are breeding, did you put tires, barrels or culverts in for them to spawn in? If so, can you remove them? Do you have dense brush or vegetation for forage fry to hide in?
What do you want out of the pond in the long run as far as fishing? If the cats are overpopulating, then I would keep each one you caught.
Can you nuke the pond and start over with a stocking plan better suited to your goals?
Lots of people on here will chime in with links to threads relevant as well as advice.
There are some really good threads on types of fish to choose and managing different fishes depending on ultimate goals for a fishery. Check some of those out.
