Mother bobcat and babies tucked into the narrow gap between two 10' high fences separating backyards in the town where I work. Both ends were sealed off pretty good, but the gap between the fences was open for the full length of the fence between the two backyards.
Pretty good sized litter. Not the best choice of location from the human residents on either side's point of view, though. I "convinced" the mother that this actually wasn't the best base of operations for her and her brood*... and within 24 hours she had relocated the kittens to a more suitable wooded creek area nearby.
* This was definitely a case of "don't try this at home". Convincing her to move consisted of me standing on the top step (the don't stand here step) of a 6' ladder and repeatedly poking her with a pole while hoping she didn't blast out of the opening and into my face.
