SPCA personnel last week found three horses and nine cattle that were apparently left at the property on Pine Valley Road, spokeswoman Beth Brookhouser said.
The cattle were all suffering from malnutrition and two were emaciated, while two of the rescued horses were extremely thin, had sand in their stomachs and were suffering from lice infestations and fungal infections, Brookhouser said.
She said the third horse had to be put to sleep due to a painful broken hip left untreated.
The animals had no food and only foul, dirty water to drink.
SPCA personnel also found a dead horse and several dead cattle at the site, Brookhouser said.
The animal rescue organization was planning to vaccinate and examine the rescued cattle on Friday.
If caught, the owners of the apparently abandoned property could face animal cruelty and abandonment charges, according to the SPCA.
Anyone with information about this case is asked to call the SPCA for Monterey County at (831) 373-2631. All calls are confidential.
