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.
Because they are biodegradable compounds, pyrethrins are now widely regarded as being preferable to pyrethroids, which is the name of a group of synthetic analogues of pyrethrin that accumulate in the environment.Pyrethrins are considered to be low toxicity pesticides from a human health standpoint.yrethrin is syntethically made by industrial methods, but it also naturally occurs in the Chrysanthemum flowers, and thus is often considered an organic insecticide, or at least when is not combined with piperonyl butoxide or other synthetic adjuvants.
