One of my very favorite blogs We Three, Ginger Cat Tales, http://wethreecats.blogspot.com/ has recently had a very interesting exploration of the role of cats and dogs in Jackie's life, and her philosophical musings about them and their personalities. She is blessed to have an amazing dog Bella who is companion, friend, and protector of her cats, and teacher to her new dog Rosie.
I don't have a dog...commuting away from home 13 hours a day doesn't make a household that's comfortable for a dog. And the longer i've had cats, the more i've come to prefer their company. However, i do like dogs (and bunnies, horses, sheep, goats, cows, etc. etc.) and i recognize that they are different than cats as is their right. Sunday we had book club meeting at a home with a Samoyed named Trotski. He's very spoiled, and wanted to be right in the middle of everything, literally--he wanted to stand in the middle of the coffee table and be petted and admired by everyone. This would be cute in a cat (in my opinion) but a little hard to ignore when it's done by a 70-pound, extremely fluffy, large white dog! He cried when he was put down in the basement and likewise when he was put outside. He kept circulating amongst the guests and ending up next to me, where each time he vacuumed most of my body surface with his exquisite black nose. Trotski was definitely picking up cat scent molecules since he spent the longest time at the places where cats sit, lean, or rub against me.
When i got home, it was a couple of hours past the cats' usual dinner hour and they were eager to be fed. Only hours later, when i was sitting at the computer, and first Fuzzy and then Louie hopped up for a lap snuggle, was i given a few cursory sniffs. (I had washed my hands...both cats sniffed spots on my wrist that i must have missed.) The reaction of each of them was clear to read "oh, you spent time with a dog. How interesting for you. *yawn* D'you think you could scratch behind my ear, please?"
