Assessment of behavioural changes in domestic cats during short-term hospitalisation.

We evaluated behavioural changes in domestic cats during short-term hospitalisation using a novel cat demeanour scoring system. Thirty-five healthy, client-owned cats admitted for neutering were enrolled. Cats were housed in a standardised cat ward for a short-term hospitalisation period (3-5 days) and demeanour scores were recorded once daily.

Clinical use of a low-dose medetomidine infusion in healthy dogs undergoing ovariohysterectomy.

Eight healthy dogs undergoing elective ovariohysterectomy were anesthetized with a standard protocol and received a low-dose medetomidine constant rate infusion during surgery.
