Why Do Cats Chase Lasers?

Laser play looks like a game, but it's mostly instinctual.

All cat parents are familiar with the eternal struggle between cat and laser pointer. For something so small and scentless, that little red dot sure can keep cats busy—in spite of (or perhaps because of) the fact that they never really can catch it. Interestingly though, there’s some debate about whether or not laser pointers are a great toy for our feline friends. So why do cats chase lasers, and is it time to ditch the laser in favor of a different type of toy?

The Allure of the Laser

Lasers are inherently stimulating to cats because of what they represent: fast moving prey. Just because your cat doesn’t have to work hard for her food (unless you count all the effort it takes to meow all morning until you fill up her bowl), doesn’t mean that she’s not hardwired for the job.

As the dot of a laser darts around the room, your cat interprets it as a small animal trying to run and hide. As such, certain inherent feline behaviors come out, notably the innate desire to hunt, pounce, and kill the prey in question. The fact that it’s merely a projection doesn’t matter very much because your cat is operating on auto-pilot, not on intellect.

How Cats See Lasers

There’s another factor at play here too when your cat chases a laser, and that’s the fact that it simply looks appealing to them. To understand why, it helps to have a base understanding of how our cats’ eyes operate and how they differ from our own.

The retina is one of the main structures of the eye. It is composed of two key types of cells: rods and cones. Rods deal with low light vision and detecting movement, while cones help the eye see color. Human eyes have more cones than rods, which means we see the world with a lot of vibrancy. Cats, on the other hand, have more rods than cones, making them experts at picking up even the slightest of movements.

What does this have to do with lasers? It means that they’re pretty hard to ignore. The moment you turn a laser point on your cat is going to pick it up in her peripheral vision, and if she hasn’t quite figured out yet that she can’t actually eat that red dot (or if she knows she can’t but doesn’t care) then that’s all it will take to start her predatory cycle.

The Debate Over Cats and Lasers

It might be surprising to hear that there’s some controversy over whether it’s a good idea to tempt your cat with lasers, but the cat-laser debate is one that has been going on for some time.

The main problem noted by cat enthusiasts who are anti-laser is that having your cat chase a laser is a form of teasing. Remember, your cat is stalking and pouncing on that red dot because her brain is telling her that it’s food to be caught and killed. She’s not doing it distinctly as a form of play, even if she’s having fun.

The laser is an unattainable target, and no matter how great your cat’s hunting skills are she’s never going to get to eat it and she’s never going to finish out her predatory cycle. Many cats figure out the ruse and stop interacting with the laser. Others find it immensely frustrating and may start behaving badly as a result. Frustrated cats act out in less than ideal ways, such as by becoming destructive or aggressive. If you notice a connection between playing with your cat and a laser and bad behavior, it’s probably time to put the pointer away for good.

To help make laser pointers more of a game and less of a tease, give your cat a treat or a physical toy right when you're finished playing. That way she’ll get the satisfaction of a “kill,” even if it’s not of the laser itself.

Laser Pointer Safety Tips

Provided that your cat seems to actually enjoy chasing a laser and isn’t just caught in an endless loop of hunt-pounce-disappointment, there’s probably nothing to be worried about. Chasing a laser is a fantastic way for your cat to get some physical and mental exercise, and also lets her tap into her kitty instincts for a bit—something that indoor cats don’t get to do quite as often as they might like to.

Of course, you should still make sure to follow proper safety tips to avoid harming your cat during play. Here are two big ones to note.

Don’t shine the light directly in your cat’s eyes. Even toy lasers emit an incredibly bright light, so it’s very important that you don’t shine it directly at your cat (or yourself!). If you do, you could cause vision problems and/or eye injuries.

Provide your cat with plenty of other toys. If the laser is your cat’s only outlet for play, it’s more likely that frustration will start to build up. Make sure that she has access to a lot of other objects for hunting and playing with, including catnip toys and wands.
