Twain had that covered too: "The dog is a gentleman; I hope to go to his heaven, not man's. "
Twain loved cats too:
“A home without a cat—and a well-fed, well-petted and properly revered cat—may be a perfect home, perhaps, but how can it prove title?”
Oh, and the following about dogs sort of belies your quote:
“By what right has the dog come to be regarded as a “noble” animal? The more brutal and cruel and unjust you are to him the more your fawning and adoring slave he becomes; whereas, if you shamefully misuse a cat once she will always maintain a dignified reserve toward you afterward—you will never get her full confidence again.”
