that's a cute story...
I have 4 cats right now.. 2 of them are lazy and all you need to do to keep them purring is have food and water ready for them and clean their... messes.. the other two are in and out all the time... My cat, Dusty just comes in for food and then she's out again, haha.. I don't know why she doesn't just hunt outside and eat what she catches.. The other cat is the only male cat we have.. He has thumbs on his front paws so we call him Thumbs. He has the most feminine meow I've ever heard from a cat, lol.... I'm pretty sure he's a hunter, as is one of the lazy ones... So, I don't need another cat, hehe...
You know what, everyone always thought I was allergic to cats.. I have four of them and I don't have a problem.. unless they sleep on my pillows of course.. I guess I grew out of that allergy... I think the only problem you'd have is if you have asthma or eczema(a type of skin rash that itches like crazy)...
