The condition of a cat’s coat is a good gauge of its overall health. Cat dandruff, characterized by a dry or oily coat with visible flakes, can be caused by anything from dry air to parasites, obesity, and serious diseases like skin cancer. Therefore, if you see these symptoms of dandruff on your cat, a trip to the vet’s office may be in order.”Many diseases show up first in the skin,” says Dr. Jean Hofve, a holistic veterinarian and author of “The Complete Guide to Holistic Cat Care.” “It’s impossible to diagnose skin disease just by looking at it.”
A veterinarian can analyze a cat’s skin cells under a microscope and perform blood tests or biopsies to narrow down the cause of the dandruff.”What we generally think of as dandruff is usually nutrition related. It is most common in overweight cats, and in cats eating mostly or only dry food,” says Hofve. Therefore, says Dr. Hofve, dry kibble should be reduced or eliminated. Kibble is low in moisture and will dehydrate cats and, in turn, their skin.

BUTTERFLY sex is not as elegant an affair as you might think. It seems that male monarch butterflies conduct an all-out sperm war based on a crude measure of how much sperm is stored inside a female from a previous mating.
During sex the males physically restrain the females for an entire day while injecting them with a fluid which contains fertile sperm as well as seemingly functionless cells without nuclei.
Michelle Solensky of The College of Wooster in Ohio paired male monarch butterflies with a selection of females that had had different numbers of partners.
She found that males could selectively increase or decrease the amount of fertile sperm in their deposits. For example, they deposited slightly more into a female for each of her previous mates (Animal Behaviour, DOI: 10.1016/j.anbehav.2008.10.026). “This may explain earlier observations that the last male to mate has a reproductive advantage,” says Solenksy.
