What's this itchy red bump on my cat's back with thinning hair?

Pets can get many types of lumps and bumps. Most of these tumors will be benign but some will be malignant and you can't tell by looks. Here is a helpful link discussing the various types of skin masses in general: https://www.petcoach.co/article/lumps-and-bumps-on-your-pet/ Since you are noticing the mass changing, I do recommend to have it checked out to be safe. The doctor may recommend to aspirate the mass to examine the cells under a microscope. That is one of the best ways to know what it is and if further action is needed. Hopefully it's nothing serious.

Hi there, it is hard to give you a specific answer regarding these bumps without seeing them, but I will try and give you some suggestions. If the lumps have just come up and feel soft they could be urticaria from an allergic reaction. Likewise if they are fairly new and are red or hot they may be caused by a skin infection. However, if the lumps have been there for a while again they could be infection but they could also be little growths in the skin. Have a good feel and if they are under the skin and soft they could be fatty lumps. If they are hard and in the skin they could be cysts, and if on top get may be warts. Unfortunately there is also the possibility the growths could be tumours. If you like you can repost with some photographs or more information and we can try and help more. I would recommend going to the vet to have he lumps checked f they have been there for a while. If they have just come up and don't look infected you could wait a day or so and give an antihistamine in case of allergic reaction.

You may look into financing through Care Credit or Scratch Pay to help assist with costs. You can find information on their websites. I hope this helps and please feel free to post any additional questions.

It is difficult to tell from the pictures, but it looks like the red area is raised which makes me worry that it is a mass. I would recommend having your veterinarian evaluate it. They will likely take a small sample of cells with a needle and evaluate it under the microscope to determine what it is and what to do about it. I would not recommend any topical treatment until we know what it is. Good luck to you and Mittens. I hope it is nothing to worry about! I hope that was helpful.

It is difficult to diagnose without seeing the bump but it could be an infection, cyst, mass, or an injury. The best thing would be to have your vet take a look at it to determine the exact cause and best way to treat. He may need an antibiotic, anti-inflammatory, or other medications to treat. Your vet can do a needle aspirate, if necessary, to help diagnose the cause of the bump.

This may be an abscess, a cyst or a tumor. You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. An abscess can usually be treated with antibiotics and/or be lanced, and a cyst can be evacuated. To identify a tumor, your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning.

Cats get a variety of skin cancers, and also can get raised bumps as part of allergies. It could be related to Jelly's itchiness. I don't think this is an emergency, but I would recommend getting him to a veterinarian early next week for a check up to determine if this a mass that needs sampled, or a allergic flare up that can be treated to get Jelly more comfortable. Best of luck to you both!
