Memory loss, also referred to as amnesia, is an abnormal degree of forgetfulness and/or inability to recall past events. Depending on the cause, memory loss may have either a sudden or gradual onset, and memory loss may be permanent or temporary. Memory loss may be limited to the inability to recall recent events, events from the distant past, or a combination of both.
Other than carrion, Opossums eat all types of small animals such as small birds, frogs, snakes, frogs, maggots and earthworms. The plant life eaten by the Virginia Opossum are fruits, vegetables, and mushrooms. Opossums are also well known to eat any sort of human food, and are particularly fond of dog and cat food.
I'm assuming you're referring to the American Opossum, not the Australian Possum. Opossums are omnivores; they'll eat pretty much anything, but they do like to eat cat and dog kibble as well as garbage, so that's why it was up by your house. They typically aren't dangerous. When threatened, their first method of defense is to run away. Second method is to play dead.
