Beware guys! I once found a charming little kitten which would chase the mouse and paw at it. I passed it onto our front office gal who thought it was just too cute for words.
After a half hour, I got a call to come help her out with some glitch. When I looked at the screen, there was a truly hard-core porn site which had somehow hijacked the cat thing! Good thing she had a sense of humor, or I might have been drawn and quartered on porn charges.
I, by the way, replicated the experiment on my machine just to be sure it, and not something else on her computer, was the culprit, and it was the cute cat.
Not saying they're all gateways to porn sites; Just beware, is all. Not everything is what it seems.
