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.
Pyrethrins & Pyrethroids What are pyrethrins? Ã¿ Pyrethrins are insecticides that are derived from the extract of chrysanthemum flowers (pyrethrum) (1). Ã¿ Theplant extract,calledpyrethrumcontainspyrethrin I and pyrethrin II collectively, called pyrethrins. â¢ Pyrethrins are widely used for control of various insect pests. What are pyrethroids? Ã¿ Pyrethroids are synthetic (human-made) forms of pyrethrins. Therearetwotypesthatdifferinchemical structure and symptoms of exposure. Ã¿ Type I pyrethroids include allethrin, tetramethrin, resmethrin, d-phenothrin, bioresmethrin, and permethrin (1, 2). Ã¿ Some examples of type II pyrethroids are cypermethrin, cyfluthrin, deltamethrin, cyphenothrin, fenvalerate, and fluvalinate (1, 2). Ã¿ Both type I and II pyrethroids inhibit the nervous system of insects. This occurs at the sodium ion channels in the nerve cell membrane. Some type II pyrethroidsalsoaffecttheactionofaneurotransmitter called GABA (3).
