Nice pics Kat!
I agree with your attitude re: the house cats--to some extent nature has to run it's course despite human feelings and attachments. Hopefully the house cats are smart enough to stay out of trouble, and hopefully the big Cats are not inclined to eat something that might sort of smell akin to themselves.
Btw, re: India and tigers, i've heard that too, but i've also heard that some of the tigers have caught on to the trick, and it's not a deterrent as they seem to be able to tell the difference after awhile--but this seems to be rare from what i've read.
Oh, i've heard that for Cougars, cinnamon actually acts more like catnip with them, than catnip does with certain other species of cats. Might be interesting to see a reaction to it on camera sometime. I learned this at the Big Cat Rescue down near/in Tampa Bay FL wherein they house many different kinds of big cats. Oddly, some big cats really prefer catnip, and some really prefer cinnamon, and i seem to remember that cougars tend to prefer the cinnamon overall.
