Cats see their Keepers as massive phantoms, givers of names and the excellent gravy of their days. Cats who have been robbed of balls and claws to not lament. They become their Keeper's keepers. When cats are hosts to fleas they assume the fleas are guests. Most cats would rather be covered with live fleas than dead ones.
Cats hold no grudges and have no future.
They invade nets of strangers with their eyes. Cats do not worry about the gurgling horrors of the disease listed in catbooks, some of which are Hairballs Enteritis and Bronchitis. But they do become very upset about Symptoms, which is the worst disease of all. They mumble darkly about radishes and death. They listen to Beethoven and become overly involved in Medieval History.
