I don't have any focusing concerns. I like the shot and love the title. What can I say, I'm a sucker for squirrels.
My concern is the composition. You are showing too much on the right. I am not suggesting a center crop, but a crop to remove some of the distracting foliage on the right.
I don't mind the DOF and understand your wanting to show the depth by keeping some of the right. But if this was mine, I would crop in the right, crop down the top and give the subject the main attention.
