Feline upper respiratory problems: observations and care

Edited by MaxTeng · Educational content, not reviewed by a veterinarian · 2026-10-26

Discharge is a sign, not a pathogen diagnosis. Breathing difficulty takes priority over identifying an infection.

Describe the pattern

Herpesvirus, calicivirus and other infectious or noninfectious problems can cause signs. Record side, timing, eye/nose changes, sneezing and oral discomfort. Color alone cannot select an antibiotic.

Know when to contact the clinic

Open-mouth or labored breathing needs immediate contact. Poor intake, marked lethargy, eye pain or worsening signs also need timely assessment; do not wait for a website recovery period.

Coordinate care

Nutrition, hydration and cause-specific care may be needed. Antibiotics do not treat every viral infection. Do not use human cold medicines, eye drops or leftover antibiotics yourself; ask what home care and follow-up are appropriate.

Bring contact history

Record actual intake, symptoms/photos, medicines, new cats, boarding, affected housemates and vaccination history. Warn the clinic before arrival. Vaccination cannot rule out infection.
