There is something in my attic!!!!

OK, so this morning I am feeding Emma but unlike every other morning I hear a very loud noise coming from the back of the house. Now let me see if I can explain exactly what I heard... It sounded like a baby calf being strangled! I think I jumped three feet in the air and then hid under the table. (Good to know I am concerned about my child's safety.) So, I start to investigate. I grabbed an umbrella out of the closet, grab Emma and start checking out the situation. The noise gets louder near the back of the house and in particular in our bedroom! At this point I can tell it is in the attic but what exactly I am hearing who knows. I am pretty sure it is some kind of animal and it is dying! This is an investigative job for my sweet hubby when he gets home but what am I supposed to do in the meantime!!?? I can't sit around here and listen to an animal die... I think I will go shopping! Oh, and whoever put a baby calf in my attic... you are in big trouble!
