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.
How to prevent pyrethrin toxicity: 1  Avoid the use of the pyrethrinâbased insecticides on your pets and in their environment if you have cats. 2  Research and consider the use of beneficial nematodes, diatomaceous Earth, and boric acidâbased compounds (e.g. Borax and Flea Busters) to control flea populations in and around your home.
