Law enforcement had to wear gas masks due to the smell to enter a southern Wisconsin home where they found dozens of cats, dead and alive.
It total, 50 live cats and 42 dead cats were removed from the Monroe house this week, the Associated Press reported.
Police chief Fred Kelley told WKOW that authorities found 35 dead kittens and six dead adult cats in a freezer, along with another dead cat in the garage.
Neighbors had complained last week about the smell coming from the home and that is when police went to the property on Monday to investigate, the Wisconsin State Journal said.
The live cats were retrieved on Monday and the dead ones on Thursday.
In court on Friday, the 78-year-old woman who resided in the home transferred ownership of the cats to the Green County Humane Society, WMTV reported.
Due to the state of the house, the building inspection department in Monroe will be demolishing the home within 30 days.
