WillFirst Strike Soft Bait Rodenticide sicken cats and birds that eat mice killed by First Strike?
Concerned that mice ingesting difethialone in house will die outdoors and be eaten by other animals who might be harmed by First Strike.
In most cases secondary poisoning is not going to be a problem unless the predatory animal eats many rodents that have succumbed to the effects of the First Strike Soft Bait Rodenticide. The exact amount of mice that must be eaten for the predatory animal to become sick will depend on the size and the health of the animal but usually they would need to consume near their own body weight of bait to get sick.
