Tom Cat Rodent baits are very good at controlling both Rats and Mice. They have a minimal bait loading and are a second generation anti-coagulant rodenticide. These “single feed” baits have a window of action that gives the target about 3 to 5 days to “leave camp”, so you have few if any dead rodents around.
Dogs are quite tolerant of this product. For example a 35 Kilogram Labrador or Shepherd dog would have to consume 8.5 blocks of bait in one sitting to have a toxic dose.
Or a ten kilogram Jack Russell would have to consume more than 25 mice and each mouse would have to have a belly full of bait!
Also cats are almost immune to this active- an average cat would have to consume hundreds of baited mice in a week to have a secondary poisoning.
