A broken pipe led to the discovery of a house full of cats with feces as high as a person's knee, according to a Local 6 News report.

Knee-High Cat Feces Found In Home

Last summer, residents of the St. Louis-area home were ordered to vacate the home in Lemay, Mo., but for some reason six cats remained.

The filth inside has been growing ever since, according to the report.

The animal waste is described as knee-deep and the stench is pungent, according to neighbors.

"I held my breath. I thought I was going to pass out because of lack of oxygen," neighbor Judy Tucker said. "It's got cat crap up to here and I'm not exaggerating."

Animal Control officers said that since someone has been feeding the animals, that constitutes 'care' so the cats can stay.

Neighbors are not happy about the situation.
