I think hugging pets is natural. But I would be very wary of kissing them especially cats. My SIL caught something off the family cat when she was in her teens which made her very ill. She had temporary blindness as well. (I'll see if I can find out what the disease is called...)
misspeaches - that sounds like the illness you get from toxocara worms - v. nasty jeannie - your cat looks the spitting image ('scuse the pun!) of one of mine.
