I think it's pretty neat. If the kitty is always right, it might give the staff more time to get the family there to say their goodbyes. I do believe pets have more cognitive abilities - likely just a different range of senses - than we give them credit for.
I am sure I have posted this before, but once I came home years ago - before Mom needed round-the-clock care - to Oberon and Titania milling around in the kitchen. It was around 10 pm, and they would normally have been in bed with Mom. They followed me when I went to check on her, and sure enough, she'd fallen in the bathroom. (She was OK, thankfully, just at an awkward angle where she couldn't get up.)
I was proud of my kitties for going for help in the only way they knew how.
