Hi. Just recently something is coming into my garden overnight and digging small holes, about 20cent coin diameter and about 20mm deep. I also find small holes or paw prints in the soil on my veggie garden. I’ve set rat traps and it’s not these. The animal even moved one of the rat traps without setting it off. Any ideas what it is please and how to stop it? Cat? Possum? Birds? Insects? They started off doing a few holes a night but last night would be 10-20. Really annoying. Thanks
