My cat has a leaking lump on her hip. What should I do before the vet?
You didn't include a picture so I cannot say for sure but the most common cause of leaking bumps on a cat would be an abscess, which is a pocket of bacteria, fluid, and inflammatory cells that is often caused by a wound (sometimes from a bite or scratch from another animal). I cannot rule out something like a cyst or a tumor that has grown too large and the skin has gotten stretched and broken open, or even a self inflicted injury from overgrooming, but the most likely answer is that this is an abscess. Pebbles should definitely be seen by her veterinarian, who will probably clean and flush the area and may recommend a culture of the area. They may also prescribe an antibiotic and maybe a pain medication, however in the meantime you can use warm compresses over the area to help it drain and to keep it clean if she allows you to. If you have an e-collar you can place that to prevent her from licking at the area and causing more bacteria (from her mouth) to enter the area. Good luck, I hope I could be helpful!
