A raccoon is most likely to win in a fight against an average house cat. Raccoons are significantly heavier (often weighing 15 to 30 lbs compared to a cat’s 10 lbs), have a stronger bite force, and use a mauling fighting style that is difficult for a domesticated pet to counter.
Raccoons are most active from March through October. Their peak activity occurs during spring and summer when mating and raising young require them to forage continuously for extra calories.
