Even fish often follow the red dot, at least until they get bored or something startles them. Some birds and small pets also show interest. But are laser pointer toys safe for your pets? Stories of retinal damage due to looking directly into a laser abound on the web and in “My cousin told me that her grandmother’s college roommate’s aunt’s dog’s sire was blinded by a laser pointer,” form.
A Pacific University College of Optometry study found that the alleged dangers of laser pointer toys have been largely exaggerated. For a human to sustain retinal damage, the study claims, the person would have to willingly look at the laser pointer beam for at least ten seconds. If that doesn’t sound like a long time, try holding your hand under scalding hot water for ten seconds! Most people would look away from a laser pointer long before staring at it for ten seconds.

Also, there remains some possibility that eye damage occurs in pets at lower levels of exposure. Therefore, many pet owners continue to avoid laser pointer toys despite data indicating that they are relatively safe.
If you do choose to use laser pointer toys with your pets, a few basic precautions are in order:
