#3 – Nocturnal Habits: Mice are primarily nocturnal, which means they’re most active during the night.

#4 – Whisker Use: Mice use their whiskers to sense changes in their surroundings and to help determine if they can fit through spaces.

#8- Communicative Sounds: Mice communicate using high-pitched sounds, many of which are ultrasonic and beyond human hearing.

#9 – Tail Function: A mouse’s tail helps with balance and thermoregulation, as it releases heat.

#16 – Nesting Behavior: Mice build nests for comfort, using materials like shredded paper, cloth, or hay.

#17 – Body Temperature: The body temperature of a mouse is higher than humans, averaging around 99°F (37.2°C).

#18 – Swimming Ability: While they aren’t known for it, mice can swim, but most don’t particularly enjoy water.

#20 – Cannibalistic Behavior: In stressful or overcrowded conditions, mice might exhibit cannibalistic behavior, especially with their young.

#21 – Great Sense of Balance: Mice have a vestibular apparatus in their inner ear that gives them an impeccable sense of balance.

#25 – Popcorn Behavior: When mice are excited or frightened, they might “popcorn”, or make sudden jumping movements, similar to popcorn popping.

#26 – Mice are “Thigmotactic”: This means they prefer to stay close to walls or tight spaces when exploring.

#27 – Ears for Expression: Mice will often express their emotions through their ears. For example, forward-facing ears indicate curiosity, while flattened ears can signify fear.

#28 – Delicate Respiratory Systems: Mice have sensitive respiratory systems, so it’s important to keep their living environment clean and free from strong smells or fumes.
