 Peter has 5 cages with rabbits (the cages are arranged in a row). It is known that there is at least one rabbit in each cage. We will call two rabbits neighbors if they are either in the same cage or in adjacent cages. It turned out that each rabbit has either 3 or 7 neighbors. How many rabbits are in the central cage?
