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.
Of all the parasites of cats and dogs, lice are the easiest to eliminate, and they pose no threat to you or your children. Treatment is relatively simple. The cat may be bathed with a pyrethrin shampoo approved for cats. After the cat is thoroughly dry, a pyrethrin spray or powder can be applied. This treatment will need to be repeated in 10-14 days since all of the nits will not be killed. Alternatively, fipronil (Frontline) has been approved for the treatment and control of lice in cats.
