without seeing a pic and going just by the sounds your saying its making it's more than likely a bobcat.... bobcats are very loud cats. if it is a cougar and it could very well be.... it's most likely a female in heat.... if you don't get it out now you might have some kittens in the future if there is a male anywhere around. if it is a female cougar then you'll proly get a male too cuz most cougar sightings are of males.... bachelor males roaming around looking for food, females, and shelter.
