Oh my Onster, your kitty hunting the spider made me crack up. I remember the good ol' days when my two still made sure no intruders creepy crawled in the house. These days I get the look that says "You gonna take care of that crawly thing woman, before it gets in MY food dish??? Don't you see I am in the middle of my 17 hour nap???"
My personal take on cat purring:
1 cat Mono
2 cats Stereo
3+ cats......Surround sound
