You may want to store your food a distance away from camp and possibly hang it from a tree off a large branch so they can't reach it off the ground and can't reach low enough to grab it from the tree branch. Bear spray could work on bears/cougars to scare them off and hopefully teach them to avoid humans. Also make sure your being diligent with your trash removal and storage. I also suggest covering your water tanks. If your using them for your drinking water its probably not sanitary for the wildlife to be able to drink from it. Plus possibility of bugs inhabiting the water, birds etc pooping in it and so on.
