Can a cougar kill a moose?

Yes. Cougars, also called Mountain lions, can kill moose by biting them on their throats and clawing the moose on the back. Most cougars prefer to kill smaller game like deer and rabbits rather than taking on a full-grown moose. Undoubtedly though, cougars are opportunistic predators and may try to kill just about any animal if it's hungry enough.
