What does the cat litter do? I've heard to use rock salt.

It attracts cats from miles around. They maintain the ground rod's
conductivity by replenishing the required moisture AND reduce the
coaxial cable munching rodent population at the same time.

It's a little known fact that coax is STILL rated in ravenous Rodent
resistance. A 50 OHM (Outdoors Hungry Mice) Impedance cable is very common.
