People living in filthy conditions in garage with smell of feces coming from it. Cats are infested within the garage including kittens and stray's. Tents set up in the back yard and animal feces surrounding fence and alley way. Not sure of who is living there, but neighbors do not want to park or go in the alley way. This is a public nuisance when they open the garage door, feed the stray cats, and we are unsure of who is in there?
