I think actually that they do it to create conversation topics for their hoomans.19 days post-chemo:
No news but good news. I've spoken to a couple of you offline about his vomiting pattern, which occurs, then goes away, then recurs sometimes. He hasn't been vomiting recently. But I am going to make a more extensive public post, dedicated to that issue, that describes his history (which started way before cancer) until now. Just in case anyone can offer any advice.
Today, he's currently at his sunning window for the ~3-hour sunshine period (if that... it dwindles by the day), just lounging and grooming.
Edit: Can anyone explain why cats always close their eyes while grooming? Is it simple eye protection (from hairs flying off)?
