Do Cows Snore?

I took our dog, Madison, out back earlier, around 10:30 pm. Since we live next to a pasture it is not unusual to hear horses or cows, even at night. But tonight, well, it was too dark to see but there was a cow not far from the fence line snoring away. I could even sense it was laying down, perhaps because of the direction of the sound. Maybe it was even dreaming because it would be loud and then softer and softer.

It was weird, I've lived here for years and never heard what I would consider snoring. Madison wanted to investigate but she's not allowed past the fence. I should have gotten a flashlight, but I had to go. I need to have a flashlight and a video camera ready for when things like this happen. You just never know.
