Nick’s comment on statite reminds me that they also don’t like digging through gravel. Thanks, everyone, for your comments. I hesitate to get cats, as I have bird baths throughout the garden and am a birdwatcher. But I wonder if I could encourage weasels to live nearby? They are tremendous hunters, if only they would hunt in my garden.
