It's getting pretty warm here in Grand Rapids. Maybe not as ridiculous as back in my hometown, but with the humidity here, it's still pretty hot. So never, ever leave your pets in your parked car. The heat sucks when you get in to leave work, doesn't it? So imagine sitting in that all day!
Check out this vet, who decided he wanted to see what it would be like to sit in a parked car for half an hour with only the windows cracked.
He should have just asked someone. It sucks.
