Mine get it quite often since I grow my own. At least a couple times a week except for winter, I pick off a few stems when I walk by the plant. The neighborhood cats have discovered it, so I now put a tomato cage upside down over the plant in the spring when it first comes up (its a perennial) to minimize damage. They (and I) can still get at the stems growing through the wire but the plant doesn't get flattened.
