I tend to be more of an introvert and my first pet was a cat. But my first dog was my very best friend. I now have one of each. I lost my shiapoo dog Lilo to diabetes a few months ago and had to give my cat Snickers to my brother-in-law because she just wasn't getting along with my other animals and I'm just too sick to handle the stress. I visit her often, but still miss her alot. I find your article very interesting and true to my experiences with cats and dogs, except I'm still an introvert and love my dog as much as my cat. But if I were to ever get another animal again, I would have to choose a cat. So I would say the survey rings true for me. As for the intelligence part, I tend to agree that cats are smarter then dogs. Thanks for the interesting article Dr. Smith. I wish you all a wonderful day with your furry friends. With love, your human friend, Renee.
