In kitties, mast cell tumors are most often seen in the skin of the head or neck, but they can occur anywhere in the body. Cats with these tumors are usually middle age or older (4-plus years of age), but any cat can develop a mast cell tumor, including kittens.
Body lice can live anywhere there is hair on the body. Body lice are much hardier than other types of lice and can live up to 10 days without a human host. On a human host they can survive for up to three weeks, laying up to 88 eggs during their lifetime on their host.ithout a human hosts, most lice will only live for a maximum of 48 hours. This is why sealing clothes and toys after infection in a plastic bag is a great way to get rid of lice. Lice on a human host can survive two or three weeks. However, living lice lay eggs.
Eggs hatch after 5 to 10 days. Young head lice (called nymphs) are mobile and molt three times, developing into mature adults in about three weeks. Adults can live for about four weeks but do not lay eggs until after seven days. Head lice do not survive off a host for more than one or two days. Head lice do not jump or fly. They can however move from an infested person to another person during play or other close contact. Head lice may also spread when an infested child shares combs, brushes, scarves, clothing, hats, towels or similar items.
