Cats
Dry mix of concrete and oatmeal, they eat, get thirsty and harden.
5 gallon bucket half filled with water with a ramp allowing rat access. They
fall in and drown if they have no other water source. Very effective.
Poison, but the dog likes it just as much. If the dog eats some, it's easily
countered with Vitamin K12 from the vet.
