Conspecific company
Company of the same species. RSPCA’s rat-company guidance means other rats, not human attention or another pet species. The word does not settle which actual animals can live together or authorize an introduction.
RSPCA uses these ideas in housing guidance: opportunities to move, hide and use resources without a layout dictating every encounter. This website cannot quantify them, certify a shelter or generate an enclosure plan.
A pigment in secretions described by VCA and MSD that may produce reddish-brown staining around a rat’s eyes or nose. The definition does not identify a particular mark, rule out blood or explain why an individual animal is affected.
A zoonotic infection can pass between animals and people. CDC describes several possible infections associated with small mammals; looking healthy does not remove the risk. Unknown means the information is not established, not that an animal or household has passed a safety check.
