A while back, it was quite evident that a rabbit had first eaten and then dug up a small bush I had planted. Since there were more holes but no more casualties, I figured all was well. A few days later--and for many days after--there were no more deep holes, but many small indentions in the ground. I really didn't think about them until Hubby motioned for me to look out the window today, I had my answer to the small holes. Birdie dirt baths!
