Is CBD oil safe or effective for my cat's persistent ear infection?
I can certainly understand your frustration. I would highly recommend not putting CBD oil in your cats ear however. If the eardrum is still ruptured, then nothing but sterile saline should be introduced inside the ear, because anything else can negatively affect her nervous system (balance, coordination, etc). Also there is no evidence that CBD oil will do anything for an ear infection unfortunately.
However, I think you should get additional testing done if your kitty isn't doing better. If an inner ear infection is present, this will be evident by a physical otoscopic exam of the ear, to confirm a ruptured ear drum, and a skull radiograph to detect fluid build-up in the inner ear. If an inner ear infection is present then oral antibiotcs, and sterile saline topically, should be able to resolve the infection. In some cases a bacterial culture of the ear needs to be done to determine which antibiotic will clear the infection successfully.
I hope that this is helpful and I wish you all the best with your cats care moving forward. If you need to discuss her case further, then don't hesitate to request a consultation request with either myself or another expert here on the site. Best wishes and take care.
