Why Rats Should Not Be Bathed: Myths and Proper Care Practices
Rats maintain coat condition, skin health, and parasite control through continuous self‑grooming. Their incisors and forepaws are adapted for precise fur manipulation, allowing removal of debris and distribution of natural oils. This behavior reduces the need for external washing and prevents moisture‑related skin problems that can arise from human‑initiated baths.. Date latest changes:
Keeping Rats at Home: Basic Care
Rats communicate primarily through scent, vocalizations, and body language. Scent marking defines territory, establishes hierarchy, and signals reproductive status. High‑frequency chirps indicate excitement or contentment, while low‑frequency squeaks often signal distress or aggression.. Date latest changes:
How Long Does a Rat Need to Recover After Anesthesia?
Inhalant anesthetics dominate rodent surgical protocols because they allow rapid adjustment of depth and swift emergence. Isoflurane, sevoflurane and halothane are the most frequently employed agents for rats.
