My cat has a red, possibly infected bump on his neck. Is it serious?

Hi and thank you for using Petco Pet Education Center, formerly Petcoach. I cannot tell where the lump is on the photo but most if not all lumps needs to be evaluated by a vet. Especially in Simba's case since the lump has gotten swollen. Your vet will perform a full physical exam and determine if the lump needs to be aspirated. Lumps can be anything from an abscess, mass/growth, hernia etc. Your vet will determine after an exam what the next best steps and treatments are. Good luck!

Thanks for including the picture of Simba and his bump. He is a handsome boy! It's possible that he scratched that area leading to trauma to the skin and the swelling. If there are other cats in the home or he's allowed outside, it could be caused by a fight with another animal. I would clean the area with warm water and antiseptic soap, and then monitor it. Should it get bigger or not go away, I would have Simba seen by a vet.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This may even be an abscess. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

Thank you for attaching a picture of Leo's bump! It could be from an injury, such as him scratching his chin and accidentally cutting himself. I would keep an eye on it for now. If it doesn't go away in the next few days, gets bigger, there is pus from the area, and/or it starts to bother him, take him into the vet. Best of luck.

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Ringo has a wound on his neck. Based on your picture, it does look like he might have a skin infection of some kind, even possibly from a ruptured abscess. Does he go outside? I would recommend having him evaluated by his regular veterinarian to have area clipped, cleaned, and assessed to determine what may be going on, and what treatment (antibiotics, anti-inflammatories, or possible surgical repair) may be needed to resolve it. If he goes outside and the wound may have come from an unknown animal, I would also recommend his rabies vaccine be boostered as well. Good luck!

Hello there, Thanks for the good photo. If it is a small minor wound like a pimple or scratch, it should be mostly healed within a week of forming. If its been present for longer than that or is worsening, I would be more concerned that it is the start of an infection or growth that would benefit from being seen by her veterinarian. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

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.
