I've found in the past that dreams like this happen 'cos I'm subconsiously worried about one of my cats.
Last week I had a dream thet I moved and someone left the door open and 2 cats got out. I went out to find them and I was going along a busy road heard that a cat had been sitting in the road and just got run over. I rushed over to the place where the paramedics (well it was a dream) had just finished with Puss - he was lying their with strteched out with no fur (like a skinned rabbit
).
There was another cat to find and I heard there had been another fatality.
At that point I woke up thank goodness.
Back in the real world Puss noticed puss was quiet and I took him to the vet a couple of days later. After a course of antibiotics he is back to his spraying, hissing and fighting self. I think the second cat is my constant vigilance over Pepsi and her breathing for which she is being medicated.
