How can I tell if an animal is rabid?

Rabid animals often behave strangely after the virus attacks their brains. Rabid animals may attack people or other animals for no real reason, or they may lose their fear of people and seem to be unnaturally friendly. Not all rabid animals act this way, however, so you should avoid all wild animals, especially bats, skunks, foxes and raccoons. Also, you should not feed or touch stray cats and dogs.
