Normal: 199 mg/dL or lower cholesterol levels. Borderline High: 200 to 239 mg/dL cholesterol levels. High: 240 mg/dL or higher cholesterol levels.

Most pyrethrin poisoning happens when a well-meaning owner uses too much of a pyrethrin-based product or uses one that is too strong for a cat. Kittens, elderly cats and underweight cats are even more susceptible to pyrethrin toxicity. This is because their bodies can't process the chemical as well, and the lack of a protective layer of fat allows the chemical to soak right into muscles and tissues.
Extensive studies of the effects of some chemical ingredients are lacking. One antimicrobial chemical ingredient known as triclosan has been identified by some as concerning.
