There is new history reported today on the origen of cats. I found it interesting but not earthshaking. They did mention how kidney disease in cats is similar to what happens in people, though.
What surprises me is that more people aren't interested in how cats can be affected by disease and the link between cats and humans. With more information coming out of China regarding tainted foods, and what happened to our pets recently, you would think more people would be interested. Maybe they will be soon.
Meanwhile, use the best quality foods you can for your cats and yourself. Only Natural Pet has an article this month about the importance of supplements and good quality food for humans as well as pets. I suggest you read that as well.
And don't sweat the small stuff! Our bodies are amazing, and God's creation contains all the cures for all the diseases - some we just don't know where they are yet. So, take a clue from your feline friend and stretch out in the sun and have a siesta, you'll feel better about everything afterwards.
