This is an incredible documentary series. Yes, I'm a crazy cat lady (but with better hygiene, less ridiculous clothes, and only one cat). Even if you're not, though, just the exquisite quality of the frames, the close-ups, the slow-motion captures -- particularly of the cheetah running at 80000 mph and of cats leaping -- is worth repeated views. I learned many things I'd never heard before, in spite of being very involved in the cat world. They also have radio collars on some cats, or left motion sensors all over for months to get never before seen glimpses of rare cats. So well done! I went to my mom's to watch it on her subscription, and I bought it as soon as it came out. Well worth the money!
