Mice carry a variety of pathogens that can jeopardize human health. Direct contact with droppings, urine, or saliva introduces bacteria such as Salmonella and Leptospira , which cause gastrointestinal illness and severe kidney damage respectively.. Date latest changes:
How mice run: features of their movement
Mice achieve rapid locomotion through a highly flexible vertebral column. Each thoracic and lumbar vertebra can rotate up to 30 °, allowing the body to bend laterally and twist during strides. This lateral flexion shortens the distance the hind limbs must travel, increasing stride frequency without sacrificing stability.. Date latest changes:
How Many Offspring Does a Mouse Produce? Reproductive Data
The estrus cycle in laboratory mice averages 4–5 days, encompassing proestrus, estrus, metestrus, and diestrus phases. Estrus, the period of sexual receptivity, typically lasts 12–24 hours, after which ovulation occurs. Cycle length can vary with strain, age, and environmental factors such as photoperiod and nutrition.. Date latest changes:
How to Feed Mice While They Sleep
Mice exhibit a polyphasic sleep pattern, dividing rest into multiple short bouts throughout the 24‑hour cycle. Each bout typically lasts 5–15 minutes, with total daily sleep time ranging from 12 to 14 hours. The species is primarily nocturnal;. Date latest changes:
When a mouse bites, the first priority is to cleanse the wound thoroughly to reduce infection risk. Immediately rinse the area with clean, running water for at least 30 seconds.

Studies identify specific alleles that correlate with extended life expectancy, while other variants predispose individuals to early mortality. Key genetic determinants include: Telomere length regulation genes that maintain chromosomal stability.. Date latest changes:
What Rats Can Gnaw Through: Potential Damage
Rats possess continuously growing incisors that extend throughout their lives. The dental tissue elongates at a rate of approximately 0.3 mm per day, ensuring that the teeth never become too short for effective gnawing. Growth is sustained by a specialized stem‑cell niche in the root pulp, which produces enamel and dentin faster than wear can diminish them.. Date latest changes:
Why Do Rats Eat Their Own Feces?
Coprophagy is the consumption of fecal material by an animal. The behavior occurs in many mammals, birds, and insects, serving as a means to recover nutrients that were not absorbed during the first passage through the digestive tract. Rats exhibit coprophagy routinely.. Date latest changes:
True rats belong to the genus Rattus , a group of highly adaptable mammals found on every continent except Antarctica. They possess a single pair of continuously growing incisors, a well‑developed auditory bullae, and a tail that is roughly equal in length to the body.. Date latest changes:
Rats require a diet that supplies adequate protein, fat, carbohydrate, fiber, vitamins, minerals, and water to support growth, reproduction, and immune function. Protein should constitute 15–20 % of total calories; high‑quality sources include soy, whey, and animal‑derived products.. Date latest changes:
Why Rats Appear in the House: Causes and Prevention
