I was very sick and in bed for about 5 days. My cats somehow got fed twice a day, and the litter box got changed in the middle (don't ask me how!).
They were on the bed with me most of the time - except when I was in my most restless periods.
I had a version of a cold, but it started in my lungs, like pneumonia. I still have a lot of congestion. I took Tylenol 8-hour (no compensation for this mention!) for the fever, and that really helped. When I remembered to take my temp, it was 100.9F, so it was pretty high for someone my age and general health. That was after taking the Tylenol, too. Goodness knows how high it was without treatment...
So, the cats really care! I had one on each side of me, most of the time. They laid right next to me, pinning me under the covers. When I turned over, they all jumped down, only to get back on the bed a few minutes later.
Beasley and Fluffy were close most of the time. Bugs would curl up in my elbow when they took a break, Princess would come check on me at least twice a day, and Queenie took a little time off from being the top-cat to check on me when Princess wasn't. In fact, Queenie and Princess are vying for top-cat position again. When they weren't really close, they were on the foot of the bed, or at the base of my dresser, which is basically in the same place but with a walkway between the bed and the dresser.
I don't know how I managed it, but I was able to keep them fed and the litter box clean. I was delirious, so I'm not really sure how that happened. Maybe my neighbor helped. She got some cough syrup for me when I ran out.
