The plank goes from outside the outer rim into the centre of the drum, and it's either too slippery for them to grip, or on a fulcrum so that when the rat walks onto the plank is drops down, the rat slides off into the drum, and them can't get out.
I met a Schipperke dog who was a rodent specialist. They originally controlled rats on river boats. He was all business and kept rats and gophers off 5 acres. I'd always thought the breed was a yappy old lady dog, but I guess they go crazy in a city apartment. (I can relate) This one came up to me, looked me in the eye, and seemed to say, "good to meet you, I'm on duty" and resumed his rounds. Not sure what I would do with a cat that turned out to be useless, but I might find it in me to be a force for selection. (take the beast to the high desert to play with the raptors and coyotes?)

We have rabbits and just moved to the country and are concerned that our stock will be killed off by any number of predators in the area. Should we add a rat terrier or 2? Our plan is the have goats, pigs, chickens, and rabbits. Thanks in advance.
You need big dogs for coyotes and I mean big (100 lb.+) GP, Catahoula Cur, and other "LGD" breeds and you need more than one since a pack of coyotes can take out even these large guys.
For rats and small predators the rat terrier is a fair choice so you might need several different breeds to get the entire set of "jobs" done.
Cats and dogs can mix on occasion. In my case any cat that did come around would either be up a tree or dead meat as soon as my LGD's spotted it. (they hate cats)
I have a Pit Bull Terrier, a Catahoula and a Boxer and a Donkey, the donkey can take out three coyotes at a time. We have a pack of about 20 coyotes in our area and they don't come onto our land. (I consider that a combination of being on top of the mountain, the fencing and the LGD/ Donkey combo, along with luck)
