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.
The Life of Lice. About the size of a sesame seed, head lice, six-legged parasites that live on the human head, are hard to see. And nits -- eggs that females glue onto hairs near the scalp -- are even more difficult to spot. But, luckily, lice can't live more than a few days away from the warmth and food the human head provides. And though they are hardy in some ways -- they can survive submersion for up to six hours (that's why swimming and showers don't kill them) -- they can't jump, hop, or fly.
