We're going to the cats and the dogs.

This sounds like an urban myth, but it was reported in a reputable newspaper. Dogs are being trained to sniff out ovarian cancer. Using blood and tissue samples donated by patients, the University of Pennsylvania's Working Dog Center has started training three dogs to sniff out the signature compound that indicates the presence of ovarian cancer.

Wow! Now when we ladies go to the doctor, we can ask for DOG scans to go along with our CAT scans.
