Authorities have taken at least 140 live cats from the property.
Investigators say they also found 58 dead cats inside the home owner's refrigerator and freezer.
"There's very little furniture inside the home, there's a lot of urine and feces everywhere you go," said humane society police officer Nikki Thompson.

A search warrant revealed that the owner of the cats had been on the SPCA's radar since January of 2018.
It wasn't until last week that a rescue cat group contacted SPCA after the owner brought multiple litters of unhealthy kittens to the vet that had a strong odor of "kitty litter and urine."
"I did know there were a few cats. We did see them in the window in that unit," said neighbor Butch Cutsler.
It's not immediately clear how or why the owner acquired all those cats.
The SPCA is continuing their investigation.
