A nationwide recall of pet food produced by Menu Foods was announced Saturday as stores such as Wal-Mart and Safeway pulled 48 brands of dog food and 40 brands of cat food off their shelves. Brands include Iams, Nutro and Eukanuba.

According to the Associated Press, an unknown number of cats and dogs had suffered kidney failure and about 10 died after eating the pet food. One Amador County resident said that number raised to 11 when her 4-year-old cat, Kaydee Mae, was put to sleep March 12 because of kidney failure.

"I feel so robbed," said Pine Grove resident Lynda Nagle.

In January, Nagle's cat became less playful and started to act sick. The cat constantly drank water and was constantly peeing, Nagle said. After her veterinarian conducted tests, it was determined that the cause was 90 percent kidney failure.

Nagle said she was also feeding her 9-year-old dog Shylo the same brand of food but noticed the dog did not like eating it so she changed it. She said she is waiting for test results to see if her dog has been affected. She said she is keeping the leftover bags she has that were recalled until she finds a laboratory to conduct tests on it.

"That little kitten came along when I was in a bad way," Nagle said. "Even though I would like accountability taken for what happened, I'm not 'sue happy' because that won't bring her back."

Symptoms for pet owners to watch for include vomiting, diarrhea, lack of appetite, excessive urination, excessive drinking, weight loss, lethargy and dehydration, according to Foothill Veterinary Clinic Receptionist Wendy Harrington. She said the clinic has had some cases and calls about the issue but cannot confirm yet if they are related to the recall. She said the only way veterinarians can diagnose kidney failure is through blood work so it can be difficult to fully treat the problem right away.

Treatment includes fluid therapy, syringe feeding and daily maintenance of medication, Harrington said. As of recently, the clinic had not received any information from Menu Foods.

As a precaution, Nestle Purina PetCare Co. and Hill's Pet Nutrition Inc. are voluntarily recalling some products produced by Menu Foods, according to an Associated Press article.

According to the Associated Press, a complete list of the recalled products along with product codes, descriptions and production dates was available from the Menu Foods Web site, www.menufoods.com/recall. The company also designated two phone numbers that pet owners could call for information - (866) 463-6738 and (866) 895-2708 - but callers kept the lines busy for much of Saturday.

Menu Foods' chief executive and president Paul Henderson told the Associated Press on Friday that the company was still trying to figure out what happened.

He said that the company had received an undisclosed number of owner complaints that dogs and cats were vomiting and suffering kidney failure after eating its products. He estimated that the recall would cost the company, which is mostly owned by the Menu Foods Income Fund, an estimated $26 million to $34 million.

Sarah Tuite, a company spokeswoman, has said the recalled products were made using wheat gluten purchased from a new supplier, which has since been dropped for another source. Wheat gluten is a source of protein.

Food and Drug Administration spokeswoman Julie Zawisza told the Associated Press it is still too early to determine what could have affected the food. Zawisza added that even if wheat gluten is the source "it doesn't necessarily mean the wheat gluten per se. It could be another substance associated with the wheat gluten."

The recall covers the company's "cuts and gravy" style food, which consists of chunks of meat in gravy, sold in cans and small foil pouches from Dec. 3 to March 6.
