Cat respiratory infections can quickly transform from a simple sneeze to a life-threatening emergency. Knowing when to seek veterinary care could save your cat's life.
Most cat owners don't realize that open-mouth breathing in cats is always an emergency situation, unlike in dogs. Understanding the warning signs of serious respiratory infections helps you make fast, informed decisions when your cat's health is at risk.
Top Questions About Cat Respiratory Infection
Is It an Emergency if My Cat Breathes Through the Mouth?
Open-mouth breathing in cats is always serious and needs quick veterinary attention. Unlike dogs, cats normally breathe only through their nose. Mouth breathing shows your cat is struggling to get enough oxygen. This can happen when a respiratory infection becomes severe enough to block the nasal passages or affect the lungs. Don't wait to see if it improves – call a veterinary clinic right away.
How Fast Can a Mild Infection Become Severe?
Cat respiratory infections can progress from mild to severe within 24-48 hours, especially in kittens, senior cats, or those with weakened immune systems. What starts as occasional sneezing can quickly develop into labored breathing or refusal to eat. This is why watching your cat closely for any worsening symptoms is essential.
What If My Cat Refuses Food or Water?
A cat refusing food or water for more than 24 hours during a respiratory infection needs veterinary care. Cats can become dehydrated quickly, which can worsen their condition. Call your veterinarian for guidance on encouraging fluid intake and when to bring your cat in for evaluation.
Can My Cat Recover from a Respiratory Infection at Home?
Mild cat respiratory infections may clear up at home with rest and supportive care, but this depends on the severity and your cat's overall health. Symptoms like occasional sneezing or clear nasal discharge might resolve without medical intervention. However, any signs of difficulty breathing, low energy, or not eating require professional veterinary assessment.
Why Cat Respiratory Infections Happen
Cat respiratory infections typically result from viruses like feline herpesvirus and calicivirus, which cause about 90% of cases. These highly contagious pathogens spread through direct contact with infected cats or contaminated objects. Bacteria can also cause or complicate respiratory infections. Stress, overcrowding, and poor ventilation increase the risk, which is why these infections can occur in shelters, boarding facilities, and multi-cat households.
Spotting Mild Cases
Mild cat respiratory infections typically show up as occasional sneezing and clear nasal discharge. Your cat might have slightly watery eyes but continues to eat, drink, and maintain normal activity levels. Some cats may have a mild cough or be slightly less playful than usual. These symptoms often clear up within 7-10 days as your cat's immune system fights the infection.
Recognizing Serious Cases
Serious cat respiratory infections require quick veterinary attention and display several distinctive warning signs. Open-mouth breathing, blue-tinged gums, or noticeable heaving of the sides when breathing indicate your cat is struggling to get oxygen. Thick yellow or green discharge from the nose or eyes suggests a bacterial infection has developed. Extreme low energy, complete refusal to eat for more than 24 hours, or high fever (warm ears, paws, and nose) are all emergency situations requiring prompt professional care.
What To Do
Step 1: Call a Veterinary Clinic Immediately
Call a veterinary clinic as soon as you notice serious respiratory symptoms in your cat. Describe your cat's symptoms in detail, including when they started and how they've progressed. Ask if you should bring your cat in right away or if there are any steps you should take first.
Step 2: Keep Your Cat Calm and Confined
Place your cat in a quiet, comfortable space away from other pets and excessive activity. Stress can worsen respiratory symptoms, so maintaining a calm environment is important. Offer small sips of water if your cat is willing to drink, but don't force food or water. Call your veterinarian for specific feeding and watering instructions based on your cat's condition.
Step 3: Arrange Safe Transport
Use a secure carrier with adequate ventilation when transporting your cat to the veterinary clinic. Line the carrier with a soft towel or blanket for comfort. Avoid exposing your cat to extreme temperatures during transport. If your cat is having severe breathing difficulties, call your veterinarian for specific transport instructions.
Potential Life-Threatening Conditions
Respiratory infections can develop into pneumonia when the infection spreads to the lungs, causing fluid buildup and severely compromised breathing. This is particularly dangerous for kittens, senior cats, and those with compromised immune systems. Without prompt treatment, these complications can become life-threatening within days or even hours.
Helping Your Pet Before the Vet Visit
Creating a Humid Environment
Run a shower with hot water to create steam in your bathroom, then sit with your cat in the steamy room for 10-15 minutes. The humidity can help loosen mucus and make breathing easier. Never leave your cat unattended in a steamy room. Call your veterinarian for guidance on how often to use this technique.
Offering Small Sips of Water
Gently offer small amounts of water using a clean dropper or syringe (without a needle) if your cat isn't drinking. Place just a few drops at a time on the side of your cat's mouth, allowing them to swallow naturally. Don't force water if your cat resists, as this could cause choking. Call your veterinarian for specific instructions on how much water to offer and how frequently.
Preventing Future Cat Respiratory Infections
Vaccinations and Stress Reduction
Keep your cat's vaccinations current, as they can reduce the severity of common respiratory infections even if they don't prevent them entirely. Schedule regular veterinary check-ups to catch early signs of illness. Minimize stress in your cat's environment by providing hiding spots, vertical space, and consistent routines. Introduce new cats to your household gradually to reduce stress-triggered flare-ups in cats who are carriers of respiratory viruses.
