Cat Upper Respiratory Infection (URI): When It’s Mild — and When to Worry
About 2 min read
Cat URIs are common and often mild, but the key question is knowing when they will pass — and when they need treatment.
Typical USA Vet Cost Ranges
Vet costs for cat URI range from $50 for basic medication to $1,000+ for severe cases needing extended treatment. What you'll actually pay depends on how mild or advanced the infection is — which depends on your cat's specific situation.
Your cat is sneezing, has watery eyes, or seems a little off, and you need to know: is this a mild URI that will pass, or something that needs treatment? A URI means a virus or bacteria has infected the nose, throat, or sinuses, causing the sneezing, congestion, and eye discharge that come with it. It's usually caused by a highly contagious virus like feline herpesvirus or calicivirus, often picked up through contact with an infected cat or during a stressful period that weakens the immune system. That depends entirely on your cat — their age, whether they're still eating, and what else you're seeing. There's no general answer that applies to every cat.
Whether this needs a vet today or can be monitored at home depends on your cat specifically — their age and whether they're still eating normally.
