i have two male cats (both fixed) and my yorkie plays with them, eats and sleeps with them 24/7. I have to worry about her whipping their butts instead off the other way around. they lay on their backs and she attacks their ears, biting and pulling until they howl...then she licks their faces to say she's sorry and it starts all over again. Mr. Cuddles was adopted by my daughter for her birthday and he was almost seven months old when we got Whiskey. My other daughter wanted a baby kitten so we got Mr. Kitty about three days before we bought whiskey for my hubby's b-day present so they have pretty much grown up together. They have not been declawed and do not scratch us, my other dogs or my furniture....they are pretty laid back. Whiskey and the cats like to have contests to see how many "presents" (mice, voles, etc.) they can bring Mommy.
