Can dogs and cats see UV light? You will be surprised

[moose1am]

I just read a article online about how dogs and cats and other mammals see with UV light waves.  At first we didn't think that they could see UV light but new research suggests we were wrong.  They can actually see UV light.  They can see urine trails according to the article.  They can see Polar Bears using UV light where they can't see the White Fur covered polar bears on a white snow background in regular light. 

Read the article in this link and discuss what you think that can do to help you improve your hunting for predators like Coyotes.

PS: I wonder if deer can also see using UV light waves?  That puts a new spin on camo clothing doesn't it now?  I wonder what my camo outfit looks like when viewing it with UV Light waves and not regular light waves that we humans see.  Ultra Violet light is a higher frequency light wave that

That's why I use detergent without UV brighteners for my hunting clothes. Deer can most certainly see in the UV range. Heck, they look right at IR trail cameras at night, and I've seen videos where guys were hog hunting with nightvision devices and came upon deer that could see the IR light source.

I saw a show about this once and it said some camo clothes come out with UV on them and if they're not washed first,deer see you as a blue thing. I bought some new coveralls after that,not thinking about it,wore them and the first 3 times I went hunting the deer showed up out of nowhere and just stared at me stomping their feet and everything else. I washed them and never had it happen again. I wash all new hunting clothes first now.

You can use a simple black light to check your hunting clothing for UV brighteners.

Not convinced UV brighteners in clothes make any difference. Called an older female yote in within 10 yards of our location while playing with my new FoxPro during Christmas. We were in street clothes with jeans that are notorious for UV brighteners lightly hidden behind some bushes with a white backdrop and full moon. She should have been able to see us for a long distance off if this theory was true but she never saw us.

I'll wash out the washing machine with UV killer soap, then wash the hunting clothes. Maybe it gives me a bit more confidence in the stand, or maybe it really does work. Either way, it can't hurt.

I've got a buddy that washes his hunting clothes after every hunt, not only the inner clothes but the outer jacket/bibs too. I think that's a bit excessive though!!

A study conducted by the University of Georgia that I read was eye opening. Deer can see into the lower UV range quite well. The same study revealed that while most of the infrared spectrum is shades of grey to them, they can see orange, especially blaze orange at 650nm. Since deer corneas lack a natural UV filter like ours they see blue and yellow well, then green to a slightly lesser degree. Red, brown, and other red spectrum colors are seen as shades of grey only. I have two UV lights that I use to check new purchases with, UVA and UVB, to reveal any brighteners, you'd be shocked by how common they are in hunting apparel.

I bought a cheap UV flashlight and found out that my ALL Free and Clear had UV brighteners in it. The reason I began using it is because the Army recommended its usage on camo BDU. Later research relieved All Free and clear sold on base has no UV but normal retail does. I have started using ECOS from Walmart (now that they dont carry Sport wash anymore)

I still have 2 bottles of that sport wash that I am hoarding.......

Infrared and Ultraviolet light waves are different.  IR is longer and UV light waves are shorter.  They are opposite ends of the human visible light spectrum. 

If deer can see UV light does that also mean that they can also see IR light waves too?  I'm asking because I'm not sure if they can see both or not. 

I wonder if they are hearing something inside the IR cameras and that is why they look at them?  If there is a capacitor inside the camera that is charging up for the flash then maybe there is a noise coming from the capacitor.  I remember when I was charging the flash for my camera it would make a very high pitched noise when it was charging up the capacitor.   I'm not familiar with these trail cameras and  don't know how they work. They are digital these days and my old camera and flash was for a film camera.  But a flash is a flash and it requires some juice to make the light.  So I figure they both have to use a capacitor to store up some electrons (energy) to generate the light.  Just now sure how much power it takes to make a IR light vs a full spectrum light.
