My cat is sick, not eating, and has a neck lump. Should I worry?

This suggests to me that Castiel has a dental problem causing this swelling and decrease of appetite such as a tooth root abscess. A decrease of appetite is extremely serious in a cat, as they will develop a fatty liver over time if they stop eating completely. A fatty liver is fatal without treatment, so that has to be avoided. Unfortunately there isn't a home remedy for a situation like this, he has to see a vet as soon as possible. I would take him into the closest vet. Best of luck.

Smok is a very handsome boy! See what you mean about this lump. It could be an abscess, it could be a cyst, it could be a lymph node swelling due to infection, or it could be related to a dental problem. It is concerning that is has kept on swelling for the past three days, and now is the time to take him into the vet. The vet is the best person to diagnose what is causing this swelling so it can be treated appropriately. I would take Smok into the vet first thing in the morning. Good luck, I hope this helps!

Yes, the mass should be cause for concern, especially since Pip has other symptoms. Have him examined by your veterinarian. A fine needle aspirate can be done in the clinic to collect samples for pathology. This may diagnose infection, a benign mass or a malignancy. Treatment may depend on the results of the aspirate. If an aspirate is inconclusive, an excisional biopsy or complete resection under anesthesia may be indicated.

Hi and thanks for your request. This lump should be checked asap by your local veterinarian as it could be tumor (fibrosarcoma). Your vet will perform some analysis to understand its nature and suggest best course of action in terms of treatment.

An infection is definitely possible with what you are describing. I also worry about lymphoma or other cancers with this sort of history, but they are not as common in younger cats. I would be more suspicious about an infection. Considering Hammy seems to be quite afflicted and there is potential for this to be something serious like FeLV, or plague, it's best to have him evaluated by a veterinarian as soon as possible. It doesn't appear to be an emergency right now, but it's best to have him seen in the next 24 hours. I hope that helps and Hammy gets better soon.

Thank you for submitting your question regarding Pillu. I recommend that he sees his veterinarian for an examination and a procedure known as a fine needle aspirate. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. This will help to diagnose the mass. He could have an infection under the skin, a benign growth or even skin cancer. Based on these results, treatment can be started if needed. I hope this information helps!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Dexter. This lump may be an enlarged lymph node if it's right below his neck. That can indicate an infection or a dental problem. Other possibilities include a cyst, an abscess, a lipoma, or a benign growth. Given it's local, I do think it's important to have it checked out by a vet, and I would have him seen by one in the next few days. I hope this helps!
