Hi CD ... this is a tricky one. As anyone reading my hubs will see I am owned by a cat, The Toof. So, I could be in trouble if he reads this, but here goes.
I do believe some people can be cat and dog people, I am one myself. And let's face it there are people out there who adore all animals, and as they often run animal sanctuaries, thank God they do!
I think people tend to pick the pet of their choice according to whether they are fastidious (cats) or outdoorsy (dogs). Even though I like both, I tend to prefer cats as I'm not too fond of the exuberance of dogs. My daughter, whilst liking cats (and horses) tends to prefer dogs. So, I guess it all boils down to the fact that there are all sortsa people out there ... which is not a bad thing, is it?
