backyard chipmunk

Last year I had only 2 chipmunks in my backyard. 2 holes in the mulch bed where the bird feeders are. I decided not to shoot them because there were just 2. No problem. This year there are about 15 holes all throughout my backyard and every week it seems like there are a few more. So I decided to take action. Problem is they aren't out when I'm waiting for them. So I randomly look out the windows throughout the day. I opened the hatchway doors to the basement today and when I came up the stairs I saw this little fellow. I had my wildcat .25 at a 90 ° angle to me while I hid on the stairs and looked through the camera.
