Why Rats Fight Each Other: Causes of Conflict
Rats maintain social order through a hierarchical system that directly influences aggressive encounters. Dominance is established by repeated displays of strength, such as chasing, mounting, and biting, which create clear rank distinctions. Individuals that consistently win these contests gain priority access to resources, including food, nesting sites, and mating opportunities.. Date latest changes:
Wood Shavings as Bedding for Rat Cages
Wood shavings serve as a common substrate in rodent enclosures because they readily capture liquid waste. Their porous structure draws moisture away from the cage floor, reducing the risk of damp spots that can promote bacterial growth. The material’s capillary action spreads urine across a larger surface area, allowing the shavings to retain up to three times their weight in fluid before becoming saturated.. Date latest changes:
