Cat NO...... I have three ferals running around in my yard this year and have had more mice and rats than ever before. I have had to put wire down in the bottom of my dirt floor coops attaching it to the inside walls, to keep them from diggin under them and coming in. Yes I had burried wire around them about 2 ft. deep but they are very crafty and went below it. Large and small rodents. I have almost finished the wire project. I even went around the eaves and have closed the small holes. What you want to bet the little ones find a way in.
First the cats will find new homes then i will put poison out for the rats.
