They banged on the back of the cage, poked the cougar with a pole, and tried sliding the animal out by tilting the enclosure, but the young cougar wouldn't budge.
The Daily Herald reports a puff of pepper spray finally drove the cougar into the woods near Arlington, about 50 miles north of Seattle.
Wildlife Officer Dave Jones fired bean-bag rounds to teach the female cougar to stay away from people. It had been captured after wandering too close to homes.
Wildlife officers estimated the 100-pound cat was about 2 years old - about the age when cougars are left by their mothers and have to find their own way.
