However, after the skunk caused them to scatter, the mother had only one kitten with her. At first, the mother didn't seem concerned, and she played adorably with one kitten in front of my camera (again, at the base of a bear-marking tree). They both rolled, showing us their incredibly spotted bellies.
A couple of minutes later, the other kitten still hadn't returned. Atypically, the mother bobcat and her kitten stayed out on the wildlife trail for hours in the same area. Usually, mother bobcats don't use main wildlife trails with their kittens until winter, when the kittens are much bigger. The mother looked around her vigilantly, perhaps waiting for her 2nd kitten to return. I wish I'd been recording audio because I suspect the mother did some cat-calling to try to bring him back.
I've made a video of all this action which I hope you enjoy watching! You can watch it at Youtube also.
