General Description: Pet mice are small rodents with round bodies, large ears, and long tails. They come in various colors and coat patterns, adding to their visual appeal. Mice are known for their curious and social nature, often forming strong bonds with their human caretakers.

Lifespan: On average, pet mice have a lifespan of about 1.5 to 2.5 years. However, with proper care and a healthy diet, some mice can live up to 3 years or even longer. Regular veterinary check-ups and a well-maintained living environment contribute to their overall well-being.

Natural Habitat: Wild mice can be found worldwide, inhabiting diverse environments such as fields, forests, and even urban areas. They are excellent climbers and can adapt to various terrains. In the wild, mice build nests using materials such as twigs, leaves, and grass.

Average Size: Pet mice are small creatures, typically growing to an average length of 2.5 to 4 inches (6 to 10 cm). Their slender bodies and tails contribute to their graceful appearance. Mice have an endearing habit of grooming themselves regularly, keeping their coats clean and well-groomed.

Enclosure Size: Provide your pet mouse with an appropriately sized enclosure that allows them to move and explore comfortably. A minimum cage size of 10 gallons is recommended, with multiple levels or climbing opportunities. Ensure the cage has secure bars and a solid bottom to prevent escapes.



Temperature Reqirements: Mice are comfortable at room temperature, ranging from 68 to 78°F (20 to 26°C). Avoid exposing them to extreme temperature fluctuations or drafts, as they can lead to stress and health issues. Provide a cozy hiding place, such as a nest box or small tunnel, for added comfort.

Substrate and Bedding: Choose a safe and absorbent bedding material for your mouse's enclosure. Aspen shavings, paper-based bedding, or shredded paper are commonly used options. Avoid cedar or pine bedding, as the strong aroma can be harmful to their respiratory system. Bedding should be changed regularly to maintain hygiene.
