Well Beelzedad since you added a smiley face at the end of your ? I'll answer this way: from being interested enough in the phenomena to research it some; it's reported over and over about this. Take for example the animals in Asia that were heading for the hills, so to speak, in the massive Tsunami a few years back; long before the people knew what was about to happen.
Since you assume Earth humans know all there is to know about the physical laws of the universe and I'm not saying they don't ; post up the scientific explanation to the animal reactions to the Tsunami so I can learn something.
There most certainly are animals with abilities humans don't instinctively have, for example, bats and dolphins hearing ultrasonic sounds, duckbill platypuses can detect electrical impulses from muscular activity and some birds navigate using the magnetic field of the North Pole.
These are not paranormal powers.
To answer your question, there really isn't any scientific evidence to suggest animal reactions to a tsunami or any other catastrophe.
What there is most certainly are flaws in the thinking that they do react to such things. For example, we would be giving animals much more credit than they deserve if in fact we assume they're running for the hills to save themselves. They really are no different from us in most regards, other than some of the examples I posted above. They just frighten a lot easier than us.
I hate it when they come in and quash a perfectly interesting question with disdain; with nothing to back their comments but opinion. There is definitely evidence that animals sense things before we do. I'm curious though, why did you mention ufos? I've never read anything about that.
Yesterday I finished our milestone and wanted to relax a bit. And then we randomly ended up having a discussion about Paranormal phenomena. My husband suggested me to watch Stigmata (which he has seen earlier). It was a...
