Rice protein has joined wheat glutton on the list of tainted pet food ingredients imported from China, according to USA Today.

Natural Balance Pet Foods is recalling some products after it found melamine, an industrial chemical, in some of its food that it suspects was in a rice protein concentrate, the paper said, adding that's the same chemical that lead to the massive recall by Menu Foods.

At this point in the game I personally have nearly lost all faith in the pet food industry to protect the health of its furry consumers. I'm also wondering if former Pres. Bill Clinton is fondly recalling the memories of all those USDA inspectors which he pink slipped. It's coming back to bite Bill now ain't it... I told you so...

I have not discontinued feeding my cats their usual commercial food. It's not that I don't love the little furballs, but changing their diet the way I'd like to would involve a small increase in our grocery budget which I choose not to bear. If the kitties were showing signs of digestive troubles or exhibiting any other symptoms, I'd surely contact our veterinarian and change their food immediately.

If I was to change my cats' diet, I would feed them human-grade salmon, tuna, shrimp, liver, beef, grains, oils and greens. Each meal would be a blend of two of the meat ingredients plus some grains and greens blended to a consistency similar to the commercial canned cat food. Wheat grass works well as a green ingredient and can be grown on your windowsill easily. As a matter of fact, it's not a bad idea to keep a pan of wheat grass growing at all times for your kitty. They love to chew it up and it often helps them to expel those nasty hairballs. Most local pet stores sell wheat grass seeds.

Due to the efforts of multiple agencies, the occurrence of these unfortunate accidents has been reduced to about 36 a year.

In 2005 about 91,000 young children visited hospital emergency rooms do to unintentional poisoning, and poison control call centers fielded more than 1 million calls. By maintaining constant availability and aggressive public awareness, organizations such as the U.S. Consumer Products Safety Commission seek to further reduce accidental poison fatalities.

To prevent these incidents, CPSC recommends the following safety steps:
