What is this raised bump on my cat's head? Is it serious?

Poor Sunny! Since the lump seems to be changing the orientation of his eye, this indicates that it is either occupying space within his skull or is putting pressure on the cranial nerves going to the eye. Possible causes of lesion include a benign or malignant mass, abscess, fungal infection, among others. Even though Sunny seems comfortable, this type of lesion is likely causing some degree of discomfort or pain. Animals are generally pretty good at masking signs of pain as a natural defense mechanism. At this point, I recommend taking Sunny to his vet for evaluation and treatment of the underlying issue. I hope that all goes well!

The black raised area could be a tumor, but all the other little ulcerative areas look like she might have a skin infection. I would highly encourage you to have her evaluated by your veterinarian soon. They may recommend removal of the black mass for biopsy. She may need antibiotics as well. Best of luck and I hope she improves soon. Thank you for using Pet Coach.

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.

It is nice of you to check up on your fiance's cat. This bump doesn't seem alarming to me. It is small, the same color as the rest of the skin, and doesn't seem to bother Shadow. I would recommend keeping an eye on this small bump for the next week or two to see if it goes down gradually on its own. If it doesn't or seems to grow or bother Shadow, then you should consider getting it tested through your vet to make sure it isn't something to be concerned about. The only thing you can do is place an e-collar on him if he does start to scratch at it. Otherwise it's best to just leave it be. I wish you all the best with Shadow. It is likely nothing to be concerned about based on this photo. Best wishes and take care.

I would recommend that Scooter have this bump checked out. An abscess is an infection, and I would not expect it to be there 6 months large. It is more likely to be a cyst or even a tumor. A vet can evaluate the bump, and may stick a needle inside to collect a sample of cells to look at under a microscope. Once they have a better idea of what it is, they can tell you if it needs to be surgically removed or not.

Thank you for submitting your question regarding Squanto. If the bump does not resolve over the next several days, then she should see her veterinarian. Lesions above the eyes can be the result of scratching due to itchy ears from an infection. Cats can be private and she may scratch while she is alone. You can also check her ears for discharge as this is also a sign of an infection. I hope this information helps!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on the images provided, it appears that there is a cyst / wart like skin mass on the head. If this keeps bleeding and opening up, I would recommend having it removed by a veterinarian in the near future. I would schedule an appointment with a veterinarian and have an exam done to evaluate this problem to plan appropriately. I hope this helps!
