I could swear our cat knew we were sick this last weekend. Me and my hubby got sick with a stomach flu type virus on Christmas Eve day (good timing eh? We missed both family get togethers
) and were sleeping and running to the bathroom most of the day and then decided that we need to stay up for a few hours that evening or we wouldn't be able to sleep that night. We sat/laid on the couch watching TV and Frankie came up and was all cuddly and sleepy by us, letting us pet him and purring. Now this isn't his normal self. Normally when we're on the couch, he's pouncing on us and only lets you pet him for a minute or two. He was like a different cat. It was very sweet.
I wonder if and how they know you're sick.
