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.
Signs of acute toxicity in mammals are the most notable. Other effects include reduction in growth rate, liver enlargement, and an increase in the activity of some enzymes in the liver. Suppression of the immune system and damage to the nervous system depend on the types of pyrethroids and the test organisms . Allethrin blocks calcium and sodium channels which underlie some of the chronic effects of low level pyrethroid poisoning .
