Question

Quizplus · Accepted Answer

When a mouse freezes, it reduces the attention-attracting effect of motion. This makes it harder for the cat to spot the mouse and increases the mouse's chances of survival. Freezing also helps the mouse to blend in with its surroundings and reduces the chances of the cat detecting its presence. However, freezing does not directly affect the effectiveness of camouflage, the levels of stress hormones, or the pheromones the mouse gives off.
