There is a medical school near where I live that uses stray cats to train students how to do tracheal surgery on babies.
Each cat is used for exactly three surgeries and then adopted out by folks in the medical school or their families.
The school keeps a huge colony of spoiled kitties in a special cattery while they are recovering/waiting to be used in the training. Anyone (human) who feels the need for a little "fur love" or a bit of stress relieving "purr time" is allowed to visit the cats at any time.
These are "excess" cats who are rescued, put to good use, and then found excellent adoptive homes.
Unfortunately, I have to call "B.S." to this post. Anything that comes out of PETA sources is bound to be misinformed, or at very least, exaggerated. PETA is the equivalent of an unofficial animal rights terrorist group. There are thousands of anti-PETA organizations, usually founded by people used to be -IN- or involved with PETA.
Little do they care to remember, we humans are animals, too. Please switch to animal rights news from an organization that is not full of crap, like ASPCA, or... well almost any other organization. If you need more evidence that PETA is bad news, look up Penn and Teller's Bulls**t episode about PETA on YouTube. They air a whole bunch of PETA's dirty laundry, including funding very real terrorist organizations, and killing shelter animals at their "no kill" shelter. And that's the tip of the iceberg. Before you call this a smear campaign, too, let me inform you that most of the information these guys used was gathered from PETA's tax forms, which must remain public because of their status as a nonprofit organization. Therefore, it can be checked by anyone wishing to do so, and thus far, not even PETA has come out and stated any of this information as incorrect.
