It was recently brought to my attention that even mainstream science recognizes cats, dogs, and other animals can see frequencies humans can't.

After reading about it a little bit, it makes sense scientifically in a separate way from spiritually. It's simple really: the scientific explanation is that cats and dogs can see UV light and a few other rays, which human retinas don't have the ability to see.

It was previously believed that all mammals had similar eyes to humans, incapable of seeing UV rays, but scientific evidence suggests many mammals can.

A study conducted a few years ago by biologists at City University London, UK provided evidence for this differential in sight between species.

According to Pet MD:

"Have you ever felt that your cat or dog can see something you don't? Well, you may be right, according to a new study. Cats, dogs, and other mammals are thought to see in ultraviolet light, which opens up a whole different world than the one we see, the study explains.

UV light is the wave length beyond the visible light from red to violet that humans can see. Humans have a lens that blocks UV from reaching the retina. It was previously thought that most mammals have lenses similar to humans.

Scientists studied the lenses of dead mammals, including cats, dogs, monkeys, pandas, hedgehogs, and ferrets. By researching how much light passes through the lens to reach the retina, they concluded that some mammals previously thought not to be able to see UV actually can."

However, I believe there is something more to this phenomena that delves into the metaphysical realm.

My little sister and I have had experiences where our cats see things that aren't there. They bat at the air with their paws, meow, hiss, and make strange noises at things that we can't see.

The most profound time it occurred was right after my grandfather passed. Our cat named Double Stuff was batting at the air, meowing very strangely, and chasing something around the room, trying to jump at it in the air, looking at this thing on the ceiling.

It was almost as if some spirit or entity was floating around on the ceiling and only the cat could see it.

There was no different UV light in my room when the cat did this: so why would the cat only at that time try to chase some invisible things?

Then a few weeks ago, my sister experienced seeing "shadow people," a phenomena commonly reported by people who suffer from sleep paralysis.

As she saw these shadow entities around the house at night (given that it wasn't an illusion), the cat started acting strange and scared. It meowed, hissed, did the same things it did before but in a scared way, not bewildered and interested.

Do you feel like some other entities exist around us, just as ultraviolet rays exist around us that we can't perceive, and only certain animals are, perhaps even only sometimes, aware of them? I certainly do from my experience.

yes animals can see and feel spirits like humans. spirits are more attracted to sensitive people or sick or terminally sick people...or mental disabled

Lets see, I have been around household pets all my life.
Not once did I have a conversation with any of them where they relayed their observations.
Perhaps we should consult Dr Dolittle on the matter?

ghosts like retards? we learn something new everyday...

My ex cat couldn't see spirits, well, not quick enough. A bottle of jack daniels fell on him, killing him stone dead

I do believe that animals like cats and dogs have eyesight that develops differently from humans and causes them to see things just a bit 'differently', and to be more sensitive to other things that get past the sight of humans.

See spirits? Not so sure. Sense them in other ways? More likely.

Just as birds can sense which way is north, feline and canine eyes evolved as they needed to in order to become more effective hunters and to spot possible threats, but I don't think they can see spirits anymore than humans can see a flavor.

Though, the fact that they can see UV light does open up possibilities and create more questions. Maybe there's another kind of life we cant see. Maybe some people have a latent ability to see UV light as well that only works part of the time and they think that they're seeing ghosts.

Only time will tell.

birds don't "sense" which way is north, they know it from the magnetic lines that envelop our planet... all animals have the ability to detect the earths magnetic fields, especially birds and aquatic creatures... but since we cannot read the animals minds, we have no telling of what they can or cannot see...

Apparently, in the 2006 tsunami in Asia, elephants sensed the earthquake and tsunami coming, it's said that they feel it through there feet!
More likely that an elephant in another country made a trunk call

yea, it's true that animals can sense earthquakes, and no one is quite sure how they do it... but one thing - animals act on instincts, something which humans don't really have to use anymore, to determine fight or flight... most human won't run or just get away from fear of social fallout...animals aren't worried about looking stupid or scared, they just care about living...

I think joking aside, elephants have very vibration sensitive feet. they feel this way in the wild, predictors etc
Good point about our loss of senses mo.

yes....i agree....they do

i lived in Naples Italy in 1973 and just before a bad earth quake the dogs all went nuts an hr before

Consider that earthquakes are tracked by subsonic vibrations.
Elephants are tuned to the subsonic - its how they communicate over long distances. So do gators and crocs.
I read a study that looked into bird song. It seems over the decades of the study birdsong has been getting louder as civilization density increases. The louder we humans get the louder the birdsong.

Our civilization methods have been reducing our sensitivities for decades. Not only our olfactory but our environmental sensitivity.
Its understandable that your pets might sense something you don't, they are still tuned to their environment.

I highly doubt they are tuned to human spirits or supernatural entities. Try to remember Occam's Razor.

But...If you need your dog to see your long dead relative and it gives you peace, go for it.

I haven't seen anything unusual in my life that has been engraved in my memory and I could label it as paranormal maybe that's because I'm not looking for unusual things to relate them to other dimentions whatsoever.

Pets also have brains like us that can fool them into percieving weird stuff or make them do strange things. Thay can be affected by drugs as well so no doing drugs around pets yea they might see or hear things that we don't, like a tiny mosquito flying around or these light beams that you said but I don't remotely recokon their perception of paranormal entities.
