Hi Josephine. In view of your cats dislike of going to the vet, the warm olive oil applied with a pipette, sounds like a very good idea. You should be able to get a small dropper, like an eye dropper from your local chemist. Then just drop about 3 drops of the just warm oil down her ears. Then just with thumb and finger, wiggle the ear near the base a couple of times, and this will work the oil down the ear. If there is any compacted wax down there, the oil will soften it and it will work it's way to the surface. Suggest leaving it then for a day, and the next day, you can gently wipe the inner side of the ear flaps with damp cotton wool, this will clean off any dirty from the surface. I hope she'll sit still while you attend to her ears, as this is probably much better than upsetting her by trying to take her to the vets. Good luck.
