Claims
*[Paraphrased derived summary — non-Open-Access source.]* Best cages for pet rats and mice are easy to clean and deodorise and resist rodent chewing or digging; solid (not wire-mesh) floors are preferred because feet and hind limbs can get trapped and injured in the gaps. *[Paraphrased derived summary — non-Open-Access source.]* Good husbandry protects rats' and mice's health: suitable bedding plus frequent cage cleaning helps prevent respiratory disease, which worsens in high-ammonia air.
