    Back to the story at hand: The owner of the dog went above and beyond and, in a search for answers, sent the applicator to a lab at a University as well as had an autopsy with toxicology done on her beloved pet. The lab tested the product and saw what they expected to see, but also saw something unusual. The applicator contained a synthetic pyrethrin called deltamethrin. This should never have been in PetArmor. At all. Ever.

    Deltamethrin is a known neurotoxin and extremely toxic to cats. Even in tiny doses it is known to be an endocrine disruptor. In pets it can cause everything from tremor, seizure, confusion, lethargy, vomiting,  drooling, head shaking and death. In cats specifically it can cause even more extreme issues.
