My pals at EWG have been talking an awful lot about sunscreen lately. That's partly because it's summer (and in Washington D.C., summer is serious business!). But it's mostly because they just released a big investigation of almost 1,000 different sunscreens -- and they've got some bad news. It turns out that 4 out of every 5 sunscreens that humans use to protect their furless skin either don't work the way they supposed to, or they've got chemicals that could make people sick over time.

That got me wondering about sunscreens for animals. After all, we like to spend time in the sun during the summer. But if no one is looking out for people sunscreen, you can bet your biscuit no one's making sure ours is any good. So I did some investigating. Read full post.
