All of the cats I've ever had over the past forty plus years, have all been relatively affectionate, and most of them have been very affectionate. Sleeping on the bed wasn't a problem for most of them, but I was rather surprised when some decided they wanted to burrow all the way under the sheets to the bottom of the bed, or waking up to cold wet nose in the ear.

That's about the worst feline generated behaviour I've ever personally witnessed with our cats.
