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.
Cats are particularly sensitive to PG and its use is not allowed in cat foods. Historically, some semi-moist cat foods contained up to 5-10% PG and cats were harmed by this (Heinz body formation). If cats or dogs ingest large amounts of propylene glycol, poisoning can occur. This is most commonly seen when pets ingest liquid propylene glycol products.
