Epidural anesthesia is a regional anesthesia that blocks pain in a particular region of the body. The goal of an epidural is to provide analgesia, or pain relief, rather than anesthesia, which leads to total lack of feeling. Epidurals block the nerve impulses from the lower spinal segments.
Tigers live for about 25 years both in captivity and in the wild. 42. Cats in general have been found to have a better memory than any other animal, including humans, being several hundred times better than dogs and dozens of times better than primates.
On average, tigers give birth to two to four cubs every two years. If all the cubs in one litter die, a second litter may be produced within five months. Tigers generally gain independence at two years of age and attain sexual maturity at age three or four for females and at four or five years for males.
