PACIFIC GROVE (CBS SF) – Monterey County officials have rescued 20 animals found locked inside filthy rooms packed with piles of clothes, trash and animal waste at a Pacific Grove home earlier this week.

On Wednesday, the SPCA Monterey County rescued 14 dogs, four young puppies and two cats from what they describe as “shocking, inhumane conditions.”

The stench inside the home was so bad that animal rescuers needed breathing equipment to enter the home. The structure was previously designated as a historic building by the Heritage Society of Pacific Grove. It is now considered uninhabitable.

The pets suffered from “flea infestations, eye discharge, ear infections, hair loss, dental disease, eye trauma and overgrown toenails,” according to the SPCA.

The case will likely be forwarded to the Monterey County District Attorney for possible animal neglect charges.
