Having a pet is no easy peasy job. Its like becoming a parent. We grow increasingly concerned on what our pets eat, drink, the toys they play with and the other pets they interact with. Fortunately there are several Regulating Agencies in the Pet Industry that drive policies and standards in this space.  
For example, in each state, Pet Food is regulated by the Department of Agriculture and the US Food and Drug Administration (FDA) in their respective States. These two state entities, State Department of Agricultures and the FDA, colloborate to form an organization called the American Association of Feed Control Officials, or AAFCO.  AAFCO develops Model Laws and Model Regulations for the labeling, sale and manufacture of commercial feed which then may be adopted in part or in whole by the states. The laws allow flexibility on a State to State level, but there are exclusive Federal level requirements that must be followed to sell pet food in the everywhere. pet food, each state may require a registration fee for each product.

The law dictates [13] that if any product claims that it is intended to “prevent, destroy, repel or mitigate any pest” then that product will be considered a pesticide. Even if there arent any chemicals in them. Law further regulates Devices and classify them as pesticides. Some common pet products that are classified as pesticides include shampoos and other grooming aids that claim to control fleas or ticks, tick powders, flea powders, collars  and certain water clarifiers and algae control products. Regulation also covers certain cat and dog behavior modifiers. Pesticides considered minimum risk are exempt from some of EPA and/or State requirements. TO qualify as minimum risk your product must be considered exempt against all the ingredients must be on the exempt list. For more information see the EPA’s Pesticide Web Site  for detailed information on pesticides.
