A couple of spots in my lawn have started to sink. Upon investigation,
I found a number of little holes, like rodents would make. I believe
the rodents have moved on -- my hunting cat used to haunt that section
of the yard from the moment she went outside, but now it no longer
attracts her -- but I still have these depressions in the lawn that are
rather hazardous to inattentive foot traffic. Is there any way to
repair them while preserving the grass?
