Some of our customers own cats and are concerned about the effects of rodenticides on their feline friend. The thought is that cats will capture and consume mice that have recently fed on rodenticide. Customers ask, "What will happen to the cat?"

The situation described above is called secondary poisoning. One of the rodenticides that we use is called Contrac, and is manufactured by Bell Labs. According to the manufacturer, a cat needs to consume 5-10% of its body weight to advise treatment from a veterinarian.

If you have a 10 pound cat, the manufacturer estimates that 22-44 mice need to be consumed, in their entirety, to effect the cat. It is not until over 44 mice are consumed, where the cat requires medical care.

We are not aware of too many well fed house cats that are interested in consuming that many mice - in such a short period of time! Once rodenticide is consumed, mice die within 5 days.

Here is the datasheet from Bell Labs: Secondary Poisioning.

We use Contrac RTU Place Packs, and Contract Blox (in bait stations). You may locate safety datasheets below from the manufacturer.
