Mice do have backbones, of course they do. Although secondary poisoning of birds is a potential danger, because of the amount of drug the cat / dog would have to consume to be secondarily poisoned from a carcass, it is extremely rare. Only if the pets are kept very short of food would they eat enough poisoned carcasses to be ill themselves. They are a lot bigger than mice.However some dogs find the bait palatable , so it has to be in a lockable trap that they con't get into. We had 2 farm dogs who were mad about dicoumarol. They would push the traps from the top of the hay in the barn onto the concrete below, and then rush down and eat the spilt contents. They did get poisoned a couple of times, but a prompt journey to the vets left them with no lasting ill-effects. After the second time, we just left the rats to do their worst (lots of loose hay)
