Our cat died back in March, and we buried him in our back yard. The ground was still partially frozen, so we could only bury him about 2 feet down. In the past few weeks, something keeps digging around his grave. We can't figure out why it started happening after 6 months. This morning it was dug up, and I went up, and it was actually down to our cat. I could see his decmoposed body (there is still some fur there). Does anybody know how to keep animals away from his grave? I keep covering it, and we put stones in the ground over him, but they keep digging there. I'm not sure what kind of animal it is.
