There is some debate, but the animal in back isn’t fluffy enough to be a wolf imo. This is in Alberta, Canada for reference. The lion just looks funny because it is blasting off with its back legs, a view you never really see. The guy who got the photo is also a veterinary virologist at the university up there, he says cougar and coyote, has other photos of yotes at that time period. All I know for sure is it isn’t a house cat @dman.
