Why does my cat have a painful bump under her ear that twitches?

It sounds and looks like Lucy could have an abscess. When cats play too rough or get bitten by other cats they can develop an abscess. With an abscess comes fever and lethargy. I suggest you take Lucy to your veterinarian for exam. If an abscess is confined, you vet may need to drain the abscess and give Lucy antibiotics and pain mets. Good luck with Lucy.

With a clean ear canal, the most common cause of tiny bumps on the ear itself is related to hypersensitivity reactions from insect bites. The inflamed and sore lesion in front of Teak's left ear is most likely due to self-trauma from him scratching. The concern is that this skin may be infected from the excessive scratching. Your best bet is to take Teak to his vet for an exam because he may need a course of antibiotics and antihistamines to manage this issue. Be sure that Teak is receiving a high quality flea preventative (such as Advantage or Revolution) monthly because flea bites can also cause bumps on the ears. I hope that all goes well!

Please understand that it's impossible to say what this lesion is with 100% certainty without examining cells from this lesion microscopically. With that said, Tigra's lesion looks as though it could be a cyst. Most cysts are benign lesions. Many rupture and some refill at a later date, but they won't go away completely on their own. It would be best to have Tigra examined by her vet within the next month or so, or sooner if it's changing dramatically or bothering her. Until her appointment, keep a close eye on it for changes, but don't worry about applying any topical medications.

Your suspicions are right. This is a skin mass unfortunately. Due to the color, I would recommend having Nanni seen by your vet and the mass sampled to see if this is cancerous or benign (non-cancerous). Hopefully it is not cancerous and we can just monitor it. But if it does end up being cancerous (after viewing the cells that make up the mass microscopically), then removal of the mass can be discussed with your vet. I wish you all the best moving forward with Nanni. Take care!

Ouch! That unfortunately should be checked out by a vet in person, especially if it's growing in size and looking more inflamed than usual, as this could indicate something such as an infection or growth that requires treatment. Typically, a vet will be able to take a sample of the area to determine the exact cells present and what treatment is needed. Until you can get to the vet, placing an Elizabethan (cone) collar on Sebastian may help keep him from rubbing or pawing at it to help it heal. Keeping the area clean and dry may also help. If you're having trouble affording veterinary care, these resources may also help so that you can get Sebastian in to see a vet: https://www.humanesociety.org/resources/are-you-having-trouble-affording-your-pet , https://www.dogheirs.com/resources-affordable-veterinary-care/

I'm sorry to hear of your concerns with Bagheera. The most likely causes for an acute swelling such as that shown in the picture include an abscess, trauma or allergic reaction. I would recommend that you have him seen by your veterinarian. They may recommend a fine needle aspirate of the swelling to get a better idea of what's going on. If it is an abscess, surgery may be required to drain the infection.

This is a skin growth and is not going to go away without surgery. That being said, I’m not sure I would rush into surgery on an older cat for what is most likely a benign growth that is more of a nuisance than it is a health problem. I would monitor it, keep it clean and if it is really a constant bother to her, discuss the potential of surgery to remove it with your veterinarian.
