Cat Upper Respiratory Infection in Shelter Settings

Upper respiratory infections spread rapidly in shelter environments and represent a major welfare challenge, with prevention and management protocols critically affecting cat welfare and adoption outcomes.

Key Facts

URI in shelter cats is most commonly caused by feline herpesvirus, calicivirus, and Bordetella bronchiseptica
Stress of shelter admission triggers URI in cats that are latent carriers of herpesvirus
Clinical signs include sneezing, nasal and eye discharge, fever, and anorexia that reduce adoption appeal
Vaccination on shelter admission reduces severity of URI but does not prevent infection immediately
Isolation protocols for URI-positive cats prevent spread but increase stress from reduced social contact
Community cat program management and stray feeding programs interact with shelter URI epidemiology

Welfare Considerations

URI in shelters creates a cycle of welfare compromise and adoption barrier. Sneezing, discharge, and reduced appetite make cats less appealing to adopters, extending shelter stays. Longer shelter stays increase stress, which worsens URI, creating a feedback loop. Well-designed shelter protocols including stress reduction, prompt treatment, foster placement, and early vaccination break this cycle. Shelter design that reduces cat-to-cat transmission through appropriate airflow management is a significant welfare investment.

What You Can Do

Consider fostering cats with mild URI to provide a lower-stress recovery environment outside the shelter
Donate antiviral medications, eye ointments, or financial support to shelters managing URI outbreaks
Support shelter trap-neuter-return programs that reduce stray populations entering the shelter system
Advocate for shelter designs with appropriate airflow separation to reduce URI transmission
Adopt from shelters with demonstrated URI prevention programs rather than facilities with endemic infection
