Your cat represents my mood with amazing precision (?)
I never had a squirrel eat an outdoor plant, but they for sure uproot them and dig them up.
A few times Ive had squirrels dig up a plant and actually plant an acorn where my plant was haha. I guess I was hogging all the sunny spots with ganja plants and the squirrels wanted to plant there oaks there.
Rabbits and deer will snack on them too, sometimes its just a free topping hehe.
For sure can usually just replant it anyway after they dig it up if, as long as your checking them often. After the plants become a certain size, its not even worth there time to try and dig it up anymore.
