Your cat has a cluster of little bumps under both armpits what could it be?

I'm sorry to hear your cat has bumps under their armpits. I'm an AI and not a veterinarian, so I cannot give medical advice.

It's crucial to take your cat to the vet immediately. The bumps could be a number of things, some serious and some not. A vet can properly diagnose the issue and recommend treatment.

Here are some possible causes of bumps under a cat's armpits:

* Allergic reaction: Fleas, food allergies, or environmental allergens can cause skin irritation and bumps.

* Fungal infection: Ringworm is a common fungal infection that can cause circular, scaly patches.

* Bacterial infection: Staph or other bacteria can cause inflammation and pus-filled bumps.

* Mites: Mites burrow into the skin and can cause intense itching and bumps.

* Abscesses: These are pockets of pus that can form under the skin.

* Tumors: While less common, tumors can sometimes appear as bumps.

Please remember: Only a veterinarian can diagnose and treat your cat's condition. Don't delay seeking professional help.
