Professional pest exterminators sometimes used chemicals called tracking powders to control
rodent populations. These poisons are meant to stick to the feet and fur of rodents, eventually causing death. Regrettably, if a cat walks through an area that has been treated by tracking powders, she may ingest the poison from grooming her feet and fur.
You need to be aware of this if you hire a professional exterminator. Of course, you can’t decide what types of rodent controls your neighbors use, which gives you a good reason to be on friendly terms with your neighbors so you can keep yourself aware of any potential hazards to your pet.
