Opossums may visit vegetable gardens, compost piles, garbage cans, or food dishes intended for dogs or cats. They also eat fresh meat and carrion and often feed on road kills.
In urban and suburban areas, opossum can become a nuisance as they often get into fights with dogs and cats and can inflict serious injury. Opossums carry several diseases such as tuberculosis, toxoplasmosis, trichomoniasis and Chagas disease. They may also have flea infestations and be a host for dog and cat fleas.
