My cat sleeps on me every night, hot or cold, and I get sooo hot.
Also, she is always right next to me, whichever room I am in, and If Im sitting down hse MUST be sitting on my lap. If Im ignoring her she sits beside my chair reaches up and "pings" my pants with her claws as if to say, hey, Im here so love me! lol. Sometimes she drives me insane, like when she wakes me up in the middle of the night becasue she wants ME to move so SHE can get comfortable, and never am I allowed to sleep in, she has me up at 7am every morning without fail to give her breakfast.
(hmm, now Im thinking, who rules my house, me or the cat??) :-)
