On average, a cat can catch anywhere from one to five mice per day. However, some cats may catch more or less than this depending on their individual abilities and circumstances. For example, a cat that is highly skilled at hunting and lives in an area with a high density of mice may catch more than five mice per day. Conversely, a cat that is not as skilled at hunting or lives in an area with a low density of mice may catch less than one mouse per day.
It's important to note that cats are not solely dependent on mice for their diet. They can also eat other small animals, such as birds, squirrels, and rabbits. In addition, many cats are also fed commercial cat food by their owners. Therefore, the number of mice a cat catches per day does not necessarily reflect its overall food intake.
