Animals and lasers

Montana64 · Sep 30, 2008

We all know that many cats and dogs love to chase "the dot". Ive played around a lot with my German Shepard, she loves to chase "the dot" from a >5mW red, but wont give my Dorcy jr (open can diode) a second look, nor will she chase a green dot. Im guessing the higher powered diodes are just too bright, causing her to not want to look at it. Im very careful to never let the dot or beam near her eyes.

Another thing ive found out is that a herd of deer (wild) are not spooked by a red laser dot shined amongst them (never at their eyes), but will scatter like a bomb went off if you shine a greenie amongst them!?!?! Weird! Probably has something to do with the colors they are able to see.

I would never intentionally harm an animal, unless i planned on having them for dinner! ;D

I noticed my dog didnt respond to a greenie at all, hen when I busted out a red it went crazy. Maybe they have wildly varying colour sensitivity ?

Because a 5mw is very dim and it looks like something that is alive on the ground(a tight little dot), a bright red/green is very bright and they can see the dot is much larger and sometimes the light pulsates or when you turn your laser they see the dot turns. They probably can't even tell what it is because it is too bright, maybe if you use a 5mw or under green in daylight where it is about the same and a 5mw red they will give chase.

That's my theory.

There are some horses in a feild behind my house which i can see from my bedroom window.

If i shine my laser on the ground they get really spooked and canter away from it to the other side of the feild ;D

Cows dont react at all to either.... probably too busy grazing to really give a s**t.

I have crazy high-prey-drive workingline German shepherds, and they try to chase, catch and obliterate any small thing moving on the ground. The laser is no exception.

Perhaps I'll get a vid, but I'm about to have to leave so not now.

I have noticed that bats love blu-ray

Every time I am outside at night shinning the blu-ray around, a bat always comes flying. It could be due do bugs being atracted to the beam causing them to fly in...but its really cool when it happens...its like a bat signal. They also seem to be attracted to 473nm but not as much, I would have to summon them first with BR and then once they are flying in the area they will react to 473nm. Strangely they don't seem to flinch for green :-?

Cats and dogs are out of the question for me as I have no "safe" laser atm

my cat was heaps scared of me when i shine my greenie knowhere near her. theres no IR filter so do you think she can see it?

I find that the higher the wavelength, (brightness and power are an issue somewhat, but not as much) the more fascinated by/scared of animals seem to with lasers.
From what I have heard, cats and dogs (and probably many other animals too, especially those that can see well at twilight and night) color sensitivity is shifted a bit higher up the spectrum than is ours. Therefore, while they can see a weak red laser, it probably isn't as compelling to them as higher wavelengths. To them, something like a blue or a blu-ray would probably be much brighter to them than it appears to us.

brtman, that's cool!

and your gif in your sig is funny as hell!

Well, I think it's prefrence and interest as no two cats or dogs are the same. Some cats and dogs don't care a rats ass for any color dot. My Pit Bull (RIP) was scared shitless of my 5mW green and would run like hell to get away, didn't care too much about 5mW red (kinda just watch it move), untill I showed her my 12mW 405, then after that she chased all colors! My cats chase the dot, but they get bored rather quickly, probably because they can never touch it. My puppy chases anything, but then she also finds self amusement playing with snails.

Yeah Ace i have been lmao for days ever since discovering it (probably really old, I am always behind when it comes to internet funny stuff), but I had to remove it cause I couldn't stop staring at it

LMAO OWNED

Shrecken, that is an interesting point now that you have mentioned it. Even our eyes perceived intensity of the higher frequencies changes quite dramatically when they adjust to the night. So a nocturnal animal such as a bat, which flies around in the dark almost exclusively (I believe that is the case with the bats in my area, sometimes twilight), would have an even more pronounced perceived intensity shift towards the higher frequencies. It makes sense. Great thinking. [smiley=thumbsup.gif]

my lab/malamute doesn't even respond to any of my lasers?

Bat doesnt like my x-75. Duck chase it at night.

Maybe it doesnt have enough mW.

Robins dont seem to care about the dot from red or green. Pigeons and doves spook and fly away from both. Black birds try to eat the dots. I've also noticed that fish try to eat the red dot, probably resembles a fish egg?

I have a small pond in my yard, i used my 5mw 635nm laser and it scares them. I point it in front of them and they swim away from it, you can actually heard them with it. Don't want to use anything to powerful, they have sensitive eyes.

Schrecken_Licht · Oct 2, 2008

I scared the dickens out of a couple of crows one day with my 5mw Core! This was in broad daylight, no less, but as soon as I shined the beam down on the ground next to the crows they just took off.....Birds have even better color vision than mammals (including people), so again, the crows' panic makes sense.
