RIP Jonesy. Have always had a special place in my heart for cats since the pair my neighbour had, both of whom had been previously standoffish, each attempted to try to climb into my lap one winter 18 years ago and sit there. Come to find out, when it happened, that they had figured out that something was wrong and that something turned out to be my heart. Got the warning while out and at a buddy's shop shortly thereafter and managed to get myself and my old 78 M/Carlo home. Had the heart attack there in the living room and the EMT's showed, up threw me in the meat wagon and off we went.. Thing is, I had been flat and lethargic but there had been no overt signs. However the cats both knew something was wrong.
Turns out that there are hospitals and LTC facilities that actually allow cats to freely roam the halls, and the nurses and ward staff watch them. If they gravitate towards a specific room or bed in a room, the staffers pretty have pretty much come to understand that that resident may not be much longer for this world. For me, even just writing this down is spooky. For their part the cats seem to like my yard and flower beds, there is a semi-feral one that lurks around periodically. it is quiet, no dogs or kids, and they like that.
