Mucus buildup in cats is usually caused by an upper respiratory infection. Common symptoms are sneezing, runny nose and mucous congestion. If your cat's symptoms get more serious or if the cat is having trouble breathing, you should seek veterinary assistant as soon as possible to ensure your pet's health and safety. If her symptoms are not serious there are many ways to help manage and treat her mucus buildup at home.

Step 1

Give your cat plenty of fresh water to drink. This will keep her from becoming dehydrated and will help break up mucus congestion causing the buildup.

Step 2

Clean your cat's nose often with a warm wet wash cloth. Gently wipe away mucus from her nose to help keep nasal passages open and prevent mucus from crusting.


Step 3

Put your cat in a room with a humidifier for about 10 minutes to help breakup mucus congestion and open nasal passages. Repeat this treatment three times a day until your cat feels better.

Step 4

Run the shower in your bathroom until the room is steamy. Bring your cat into the bathroom and let her breathe in the steam for about 10 minutes to help loosen mucous and moisturize your cat's nasal passages

Step 5

Tap one side of your cat's rib cage gently with your hand in a cupped position to break up mucus. Do this to each side two to three times a day to help loosen mucus and ease congestion.
