Just seen this: http://www.bbc.co.uk/news/science-environment-22567526 If you click on Orlando the cat, you can watch a first-person perspective of a cat throwing up. Immense.
If only.......LOL. I watched the Horizon episode and........after a lot of expensive analysis and field monitoring they came to the same conclusion that almost every single person I know (cat and dog owners alike) know about cats and always have done. They love not the owner, They tolerate the provider. They did give stage to the cat owners and a pet detective (LOL), At times I thought the show was more about them than the cats. My advice, Don't watch the BBC version, Nexxo's link is lot more entertaining
