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. A person with desirable (normal) total cholesterol levels is usually at low risk for heart disease (this depends, of course, on their total risk profile).
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.
Certain species of the chrysanthemum flower have been used for hundreds of years as insecticides and repellants. The naturally occurring chemicals obtained from these flowers are called pyrethrins. Pyrethrins are one of the most common ingredients used in flea and tick control products for pets today. They work by disrupting the normal function of an insectâs nerve cell, causing it to fire impulses non-stop â ultimately leading to the insectâs death.
