Hehehe. One of our cats died recently at 16. In her prime she was one of the biggest cats I have ever seen(solid muscle wise) and thought she was a dog. Now, we have goats and had 2 dogs, both were large working dogs and goats are, well they're goats. If you've never owned goats you dont know what they're like. If you've ever seen a cat attack a goat you know the meaning of funny. If you've seen a cat chase a dog into the goat pen and then the dog is charged by the goat, well, it makes me laugh to remember it.
Our other cat is afraid of everything, probably the effect of living with the other cat for so long. On the smart front though, she's king. As FlyingThingySittingSomething was saying, cats probably think they can talk, the siamese sure does. Theres nothing more annoying than a bored siamese who knows you're home somewhere and is trying to find you. Loud, very loud.
