Just seeing a typically nocturnal animal outside during the day does not necessarily mean that animal is rabid. For example, during the spring and summer it is quite normal to see an adult raccoon out during daylight hours. The spring and summer is the height of raccoon baby-rearing season, so mother raccoons will utilize any opportunity – regardless of day or night – to find food, or even just take a break from the kids!
Likewise, while coyotes and foxes are most active at night, they will be active anytime food is available. For example, a portion of their diet consists of squirrels and rabbits. So a coyote or fox out during the day may simply be in pursuit of a squirrel or other small mammal, or be taking advantage of cat food or dog food that people put outside on back decks.
Opossums are occasionally found on fences or in trees after they have been chased by dogs. Usually, opossums are still too frightened by morning to come down from their safe spot, and often will wait until the following night to return to their den.
