Felik uses the same Class 3R (Class 2M in EU) laser module as most generic laser pointer products and existing laser toys on the market. While you certainly don’t want to be looking directly into the laser beam, they are all certified safe for brief exposure.
What makes Felik even safer than other pet products is by the way in which it actively runs away from your pets (and humans). Other pet toys which don't track the animals may inadvertently shine the laser into your pet’s eyes.
