My perfect cat would have the following:
sex: male

appearance:shorthaired reddish orange with blue eyes

personality: very affectionate and loving, a lap cat, likes to cuddle in bed, playful and entertaining, has a loud purr

other: comes when called, always uses the scratching post, always greets me at the door, isn't too demanding, gets along well with other animals, cleans up after itself

I don't think that a cat like this exists but one can dream.
