Ok, I was in the chat channel talking to some guys about a possum harassing my dogs. Tonight I went outside around 9:00pm and smelled an awful garbage/rotten produce smell and was wondering what it was and did some yard searching. There's a faint trace of the odor in my garage but hardly noticeable and its extreme outside is it some sort of animal?

P.S.

One of my dogs were runnin around the yard huffin and puffin, And my house cat keeps tryin to scale the garage so any ideas?
