They are indeed. In Ontario, the main concerns are foxes, racoons, skunks, and bats. So I am glad my cat was smart enough to nope out. It was only his body language that made it amusing. Always with the sweet murder-chirps watching squirrels out the window, and when he gets his chance to unleash hell, he wants no part of it. Good times.
For what it's worth, I lived in a big, old house renovated into apartments at the time, so I suspect the bat crept down from the attic. I was there for four years and that was the only pest I dealt with. I miss that apartment ... because it was super cheap.
