No. In the dark, the eyes of animals, especially animals that are nocturnal, will reflect light and look like they glow. This is the same thing that causes your eyes to "glow" red when someone takes a photo with a flash.

Cats' eyes do not literally glow in the dark as they do not actually give off their own light. The glowing effect is caused by a light-reflecting surface in cats' eyes behind their retinas that helps them to see well in the dark.
