I was in the hospital for 4 days last week with an infection on my face (it swelled up). well it doesnt seem to be going away (even with meds) so i will be going back to the hospital. anyways, i have been really tired and have been laying around alot this last week and i have noticed that my cat is hanging around me more, wanting me to pet her... do you think that cats and dogs know when their owners are sick? does anyone have a similar story to tell? this has got me curious.
