Companion Animal Practice
Rhinoscopy in the cat
  1. Nigel Harcourt‐Brown

    Nigel Harcourt‐Brown qualified from Liverpool in 1973. He runs a busy four‐person first‐opinion and referral practice in Harrogate, in partnership with his wife, seeing dogs, cats, rabbits and birds. He was awarded an FRCVS in 1995 for his thesis entitled ‘Diseases of the pelvic limb of birds of prey’, and is a past recipient of the Melton award and William Hunting award. His main interests are surgery and endoscopy.


THE use of rhinoscopy to diagnose the causes of nasal discharge in dogs has been discussed in two recent articles (Harcourt‐Brown 2006a,b). Cats may also present with chronic nasal discharge, which may be unilateral or bilateral. There are similarities between dogs and cats with this problem but there are also differences, as discussed in this article. Despite the smaller size of cats compared with most dogs, it is still possible to make a diagnosis in the majority of cases presenting with chronic nasal disease using a rigid endoscope; flexible endoscopes are usually too large to be useful.
