I think it is fabulous. My dog (nothing like cancer) smelled an intruder who was three rooms away and on my cement porch. I don't "think" she heard him first, I think she smelled him. That was her first sign and when she did that, all of my cats picked up on it and ran for cover. I am amazed on a daily basis how smart they are.

To be able to tell a woman that she's going to have a seizure is so wonderful......Hurry for animals!!
