We do see coon and possum poop once in a while, but not so much since DH has been trapping them. We're on the western edge of woodchuck distribution. I did see a couple poops but they were tiny! Maybe half the length and width of your pinky and very seedy. I'll take a pic if I see it again. It's been so dry that there aren't any tracks.
The only thing different this year is that I'm using soybean mulch which does have stray soybeans in it. I've chased a squirrel out of the garden several times. Maybe he's psychotic... Last year they did a good job of tearing up my sunflowers.
I've found about a dozen chewed lilies now. This one was too far gone to save by the time I noticed it.
Here is a bite take out of a tree
A couple more lilies with just the buds eaten ~ over 2' tall. Foliage is untouched.
