Household pet care now carries unseen ecological consequences.

Flea prevention is marketed as routine care, but veterinarians across the United States are sounding alarms about consequences far beyond household pets. Chemicals designed to kill parasites do not stay contained. They wash off, spread through soil and water, and enter food chains. Wildlife rehabilitators are reporting unexplained deaths, population drops, and neurological damage in species far removed from dogs and cats. What appears safe at the kitchen counter may be reshaping ecosystems nationwide, raising uncomfortable questions about convenience, oversight.
