Editor’s note: In this prospective cohort study, 60 healthy adult cats that were admitted to an animal shelter were monitored for 3 weeks upon admission in order to identify a potential association between behavioural stress, food uptake, changes in body weight, and the development of upper respiratory tract infection (URI). All of the cats were weighed on the day of admission and on days 7, 14, and 21. Body condition was scored using a scale ranging from 1 to 9, with a score of 5 considered to be optimal. Stress was scored every morning for the first 7 days using a cat stress scoring system that ranged from 1 (fully relaxed) to 7 (terrorised). Food intake was assessed subjectively using a scale ranging from 0 (not eating) to 2 (eating normally). All cats were examined daily for the presence of URI.
