I don't know if any of these are copywrited but I have framed art with....

"Cats are like potato chips, it's hard to have just one"

"A cat hold infinity in her eyes and your heart in her two front paws"

"No Heaven can Heaven be, it my cats are not there to welcome me"

"People who don't like cats were mice in their past life"

"A cat's purr is just happiness rumbling under it's fur"

Is this what you were looking for?
