Squirrels

For some reason squirrels always come into the garden and dig through dirt that I've recently planted or turned over. Sometimes its not a problem because I can just fill in the holes, but sometimes the squirrels dig up the seeds, either intentionally or unitentionally. This time they dug about 6 holes, but luckily they didn't dig up any seeds. This is one example hole.Muffin asleep on the job.
