Hi. If it is a tick, upon closer inspection you should see legs (I think 6); the head won't be visible. If for some reason Bravecto isn't working, the tick will become engorged by feeding off your poor baby's blood - so, look for it to grow in size. I think it will fall off on its own if the Bravecto is effective as it will stop being able to suck blood as it dies.
Odds are it is something else - could be a cyst, wart, or some other type of growth. Hopefully, other members will come along soon and offer their input!!
Not a tick. I don't see legs and it looks like a cyst or growth of some sort. There also appears to be a small indentation and redder area in the middle.
Thanks FeebysOwner, Purr-fect and fionasmom. The growth on the cat's ear almost doubled in size within 24 hours of my post. Soon after that it looked like the cat scratched it open, quite a mess. It slowly started to get better and now is almost completely healed.
Thanks for the update! Sounds like it could have been some sort of wound that became abscessed. They will swell in size and eventually burst open - scratching would certainly help that process along. I am glad that it didn't become infected and require more extensive treatment, given you are saying it is nearly healed now. I assume you kept it clean after it broke open? Just continue to keep an eye on it to make sure it doesn't reappear - indicating there is still pus in the underlying tissue and that it would need to be treated in order to entirely get rid of it.
