TEMECULA, Calif. -- More than 100 cats and dogs were euthanized Friday night after authorities found them living at a filthy Temecula home.

It all started when a neighbor complained about two vicious dogs running loose in a mobile home. Animal control officers investigating the claim around 11:45 Friday morning discovered dozens of dogs and cats both dead and alive.

Temecula animal control officer Jack Nelson said, "It felt like an earthquake with all the dogs inside. We just both looked at each other and said, 'oh my God, do you hear that?'"

There were more than 100 feral dogs and cats running wild inside.

"My eyes burned so bad," Nelson said. "It's probably one of the worst smells I've ever encountered."

The animals were placed in makeshift kennels inside and near the Temecula mobile home.

Nelson described the scene: "[There were] 40 of them in that one pen, in another pen they had two dogs. In another pen they had 15 dogs at least, and as we're walking around to the back you could smell death."

Among the malnourished animals were decomposing dogs and cats.

Nelson said he and his partner witnessed something they will never forget while they were on the property: a pack of dogs killed one of their own.

"Within an hour they were eating the dog," he said.

Elisao Jimenez, the 66-year-old who lived on the property and owned the dogs, has been arrested and booked on suspicion of animal cruelty.

"Its a shame," Nelson said. "A lot of those dogs could have been saved if he'd have just called and asked for help."

Willa Bagwell, the executive director of the Animal Friends of the Valleys, says Jimenez told her the situation got out of hand.

"He started with a few; they started inbreeding. He didn't want to bring them to a shelter where they would be euthanized," Bagwell said.

Only nine puppies and the owner's personal dog, Johnny Otis, were spared.

"It breaks my heart that those animals lived that way," Bagwell said. "There's no reason for it."

The nine puppies are being sent to foster homes until they're big enough to be adopted.

Ten-year-old Johnny Otis is available for adoption. If you are interested, contact the Animal Friends of the Valleys at (951) 674-0618.
