Hello, this is one of the reasons why CEMENT is better, liners are faster to install and cheaper ( to some degree) but this is one of the problems that come with liners. One solution is to lay about a 2 inch or more layer of cement under the liner and this will stop the mice, or about 3 inches of heavy crushed gravel. You have provided a good safe place for the rates, they have shelter, water and food! Try to also kill of the mice or rats with poisons!
