We are out in the country so they have a good food source of mice and moles from the farm land. So we make boxes for them in the winter and put out some food once a week just for supplemental food source for them. They are good kids and if we can we get them fixed, they do a big open call for them a few times a year and they just call us and are like how many can you get and send us over lots of carriers. Then for a week our house is just FULL (we have the main house, the barn and a chicken coop to keep little ones ) till we are sure they healed correctly then as they can they leave.
