This might be rather difficult to admit (seeing as I very rarely admit that I'm wrong), but I have finally come to my senses, Mssr. Potter and Mssr. Black. Having a family cat is an atrocious idea! Not only would it ruin the couch by scratching it all to pieces and getting its hair every where, but it would also run off our regular company! And goodness knows, if we did get one, my sister would feel more inclined to come over. She would likely draw the conclusion that we have gotten rid of our "mangy black dog that smells of something awful" and came to our senses and gotten an "adorable kitten who is superbly well-mannered."
So, on the basis of keeping my sister, her husband, and their never-satiated son away from our house as often as possible, I concede, gentleman. No animals of the feline variety will ever (willingly and knowingly, mind you) be brought into our house.
Now, I'm sorry for the insensitivity and for quite clearly going a bit batty. And yes, you might want to mark this rare day on your calendar.
