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.
Acetaminophen is the active ingredient in Tylenol and some other related medications that are used to treat pain and fever in people. Unfortunately, this drug can be extremely toxic (poisonous) to cats and dogs. Acetaminophen toxicity occurs when a cat or dog swallows enough of the drug to cause damaging effects in the body. Acetaminophen is mostly metabolized (broken down and eliminated from the body) by the liver.
