Foxes were made for that

Very true, but then how do you get rid of the foxes?

Foxhounds?

But then how do you get rid of all the foxhounds?

Solid Snakes, maybe? Or Lions?

In the event the lions take over a school of Tuna develops a taste for lion. They use kelp to create Tuna breathing apparatuses and establish a beachhead to launch their lion attack.

Domestication

Foxdie obviously

Just build a decent coop from the start to keep chicken safe at night, and let the foxes roam freely the planet eating as much mice, voles and rats as they can catch. They love that job.

Ms yellowkitty will develop quick the sense to keep away from its path, or show their nails, or climb a tree.

Envious. That wasn't possible in my case although I also did it myself. I killed hundreds using 30 lbs of dry ice. The city parking lot nearby had dozens of nests I mapped and sealed.

Btw, how did you "catch" them? Were they Norwegian rats?

How do you kill rats with dry ice?

Dry ice is frozen CO2. Rat nests usually have two holes, an entrance and an exit. Close one, place dry ice in the other and close the other hole to seal it. The dry ice melts and floods the chambers with CO2, no more rats.

It's considered more humane and safe than poison. Some cities use this method.
