At the local vet emergency clinic, they have two live-in cats that are on duty all the time to give comfort and give blood!

Both cats are very good at dealing with lots of strange animals coming in, and lots of noise and excitement during an emergency. Apparently their calm temperament lets them relax through the adventure of giving blood too.

Animals have given so much to human medicine. I hope we keep using technology from human medicine to help the animals in return!

P.S. Anyone that has a heart pacemaker can put in their will that it be donated to a vet school to be used for dogs. The pacemaker can't be reused by a human, but dogs can receive them and get a new lease (leash?) on life!
