Reply to your cat having a lump inside the ear by: Mary in NC
Hello I have worked in Cat Rescue for many years and am currently enrolled in a Vet Tech Class. I have seen this alot and even had 2 of my own cats develope this or something like what you describe.
I am not a Vet and it is always best to have a Vet see your pet first but my cats developed what is called "Ear Hematoma". This is a bubble type lump on the inside of the cats ear on the inside of the ear flap. The bubble is spongy and warm to the touch and this is because it is blood filled.
This is caused by excessive shaking of the head....usually caused by an ear infection or possibly ear mites. The excessive head shaking causes a rupture of a tiny blood vessel inside the ear flap and it fills with blood. These Ear Hematomas can be variable in size. My cats had one that got to be the size of a nickle and they appear and fill fast once the rupture occurs. My vet said they are alittle painful and uncomfortable for the cat. By NO means should you try to drain them yourself! My vet numbed my cats ear and lanced it, drained it and sutured it back and it healed nicely with no complications. But again let me state that this is somthing that ONLY a vet should do. Its not a life or death thing but not something that feels good to your cat if untreated.
I hope I helped you with this info but always the best action is seek advice from your vet FIRST.
Good luck to you and your kittys.
Mary
