I've read the whole thing and was thinking to myself before the vet quoted that I thought alot of animals can do these things. No-one has just ever been in this siuations where there are so many deaths and a cat that can wonder around freely.
There have been many TCS members that have become ill or injured, and their cats have started acting differently around them.
That article was published in Denmark in July - he was dubbed Dr Død (Dr Death) but I think it's comforting for people to have a little warning when their loved ones are going to pass on. He's almost like a modern day guardian to the gates of Heaven, come to guide souls on to the next life. I find it all very romantic. Morbid, but romantic. Sure he's not very sociable, but I think I would like a soul like that to come and take me away.
