Cat gravity, indeed. 
I highly recommend the book to catlovers–the illustrations are very cute, and the text is so true!
I once read that Mohammed cut his sleeve off rather than disturb a cat that was sleeping on it.
I try not to disturb cats unduly, but I have no qualms about eviciting a kitty from a chair. The Innocent Schoolgirl’s roommate, however, has a cat named Wells Fargo. He’s a handsome and loving kitty, and one day he decided to occupy the chair in front of the roommate’s computer. She moved him, only to have W-F reclaim it as soon as she got up. She went and got another chair (she uses cheap folding chairs and just happened to have another of the same kind on hand.) and sat in that one instead. Now, there’s two chairs in front of her computer: one for her, and one for Wells Fargo.
My parents’ boy dog is a serious cuddler. If you get up on “his” couch, he will curl up against you, with his head on your knee.
And fall asleep, head getting heavier, and heavier. But that’s okay, even when he’s knocked your leg out completely (asleep all the way to where his head is).
It’s the fact that he drools, and his nose runs, that causes issues. Because you can’t just /move/ him…
My husband was trapped in the recliner just last night. He had one on his lap and the other was sleeping under the foot extension, so he couldn’t close the recliner to get up and get something. Well, of COURSE I dropped what I was doing and came to his aid, waiting on him hand and foot so he wouldn’t disturb the 22-pound wheezing behemoth.
Our oldest cat, Arlene, is eleven years old. I had been recovering from my recent hysto and was laying in bed, and Arlene was sleeping with me at the time. I needed to get out of bed to use the bathroom, and so as not to disturb her, I had to manuver myself into a few odd positions to get out of bed. It wasn’t exactly comfortable to do, but I managed to get out of bed and go on to the bathroom, without disturbing her.
It seems that, when I stretched my legs getting out of bed, I somehow tore/opened up one or two (or more) of the sutures inside my vagina (In the area where the cervix used to be) and bled quite profusely until I could get to my gyno’s office to have it ‘fixed’ that day.
After Glenn got out of the hospital last year, I slept on the couch several times because he was in my bed and I felt even more guilty than usual about moving him. He no longer lets me make my bed in the morning; I have to make a little nest out of the blankets for him to sleep on during the day. He will loudly mrroww if it’s not fixed just right. Since we have to monitor how much he eats in order to judge his insulin dose, he is actually in the living room most of the day while the other cats are shut in the bedrooms with their own food, water and litterbox, so there is also a second blankie-nest on the couch. Now when I go to bed I will carefully lift him, pull the blankets up, and put him back where he was. Sometimes he’ll stay, sometimes this causes him to find some other place to sleep.
Allessandro has too short an attention span to really bother with this. You can shove him off the chair guilt-free because he’ll forget that he was on it as soon as he hits the floor.
Riverbed will usually make room if she’s in the bed. If, however, I am laying on the couch and she decides to nap on my stomach, forget it. She’s defintely the type that if I sneeze, she’ll run away, but if I really need to get up, nothing will dislodge her. She also has a habit of doing this so that her butt is in my face or tucked under my chin.
I’ve been needing to take some cold medicine for 2 hours now but I don’t want to disturb my cat on my lap…rediculous
Okay, I’ll admit that the kitties walk all over me. Often literally so. But when someone (not mentioning any names, Tikva and Enigma) won’t move their large fuzzy butts off the book I’m reading, there’s only so long I’m willing to wait for you to MOVE before pushing you off.
(Someone, someday, will invent a glass cat that we can read through).
If it’s a zombie cat, then yeah, I’d avoid disturbing it 
FYI this thread is 11 years old.
The cats I had when this thread started are long gone. No one’s disturbing them now.
I couldn’t disturb my sleeping cat even if i tried. That’s a damn lazy animal.
Since this is a zombie thread which should quickly sink, I guess I can confess one of sins:
I sometimes will poke one of my two cats when he is napping because he makes a hilarious half-asleep-offended-old-man grumble when disturbed :D. I can’t do it too often or hard, because then he just wakes up and spoils my fun. But the occasional light poke just to hear him complain in his sleep is pure gold.
I wouldn’t even disturb our neighbor’s cat when it came in for a visit let alone my own pets unless it was good damn necessary.
You never know what’s gonna set 'em off.
My dog is up in a second if I come anywhere near her.
