Hilarious video! Seriously, cat's can make the freakiest noises. When our cat's been in heat I have heard this freakish voice saying something that sounded like, "Mommy!" I would get up thinking it was one of the kids, but found out it was just the cat rolling around and yowling. She sometimes even sounded like she was yelling, "Oh no! Oh no!" The worst part is when she would stand on my son's bed, look out his window and yowl in his ear.
One of my cats howls outside like a dog.
