Interesting article, Mel, and you offer valid perspectives. I like both cats and dogs, and appreciate their differences. I currently have three cats and one dog. Cats are much more independent and you will be fine if you have to go away for a few days, as long as you leave them food and water, whereas a dog will fret.
Both give their love and attention in different ways, but it is hard to resist the contented purrs and rubbing up against you of the cats.
My dog follows me everywhere in the hope I will take her for a walk or play with her. I enjoys doing these things, but not all day or when I am busy writing etc. Fortunately the dog Honey and our youngest cat George are best friends so often play and sleep together. So, now I get a break occasionally.
