Here's a cute story about cats and sleeping post-op in a recliner or in bed from one of the VR.com members:
While I used the recliner a lot during the day, I couldn't sleep in it due to being visited by cats (some rather more than 10 lbs.), I slept mostly in bed. Back sleeping resulted in snoring loud enough to wake me up, so Laura used various wedges of blankets, towels, and pillows to position me for comfort--about halfway between back and side. On cold nights she would also microwave a buckwheat pillow for me, and I would use it as necessary for warmth (heat lasted for hours).Strangely, it was a heart-related incident that forced me to use a recliner. Back up in Anchorage in 1996, shortly after I noticed a rather abundant number of PVCs during our very stressful move and drive to Anchorage from Idaho, I wore a Holter monitor for 24 hours to record my heart action awake and asleep. I couldn't lay down in bed, since the device was too cumbersome, so I wore a bathrobe, placed the main monitor into one of its pockets, covered up in my Lazy Boy recliner, and managed to get a reasonably good night's sleep. There were cats then, too, but I could take a nighttime 'visitor' or two--just shoved him or her off when too warm or heavy. Amazingly enough, three of the six cats we had then are still alive, including one that's now 18--and she's in great health. Of course after the OHS, circumstances wouldn't allow me to free myself of heavy cats, so I couldn't take the risk. Anyway, Laura made the bed nice and comfortable, and it made her feel a lot better to be beside me in bed--and me, too.
