MONROE, Wis. (AP) — Authorities have removed dozens of dead cats from the freezer of a home in southern Wisconsin.

Police confiscated 50 live cats from the residence in Monroe earlier this week. Authorities say when they executed a search warrant on Thursday, 35 kittens and six adult cats were found in a freezer. They also found a dead cat in the garage.

WKOW-TV reports firefighters wore gas masks and oxygen tanks to enter the residence because of the smell. Police Chief Fred Kelley says one of the 50 cats taken Monday had to be euthanized because of its poor condition.

In addition to the 50 live cats seized Monday, 42 dead cats were removed from the home Thursday.
