Allerca cats, firms capturing the benefits from innovation

My book Freedomnomics has a paragraph on the fact that patens may not always be enough to capture the return to innovations, but that companies have still figured out ways to capture the benefits. One case that I pointed to regarding Allerca cats, which were neutered so that those who bought the cat wouldn't be able to breed them for resale. A picture of one of the first cats can be seen here. By the way, it is a very cute cat.

UPDATE: Science Blogs has pictures of multiple cats up. They also note that Time magazine found that this was one of the best inventions of 2006.
