Well, we have ours. I am not a doctor and I'm not going to tell anyone what I think they should do. What I will do is give the info I have.
1% injectable from the feed store is sterile and is 3 mg/ml. I am sure you should not inject it but if you take it by mouth....3mg/ml is the info you need. A 250 ml bottle was 65 bucks. 1/10 a ml will eliminate within a day, ear mites in cats and dogs. Just squirt it in their ears with a small syringe or dropper.....small syringe is best, like insulin syringe.
I saw this tonight and like the above text, I ain't suggesting shit to anyone but I will say we just got over it the second time and if we would have felt REALLY bad I would have blamed it on "worms" and not hesitated to take it.
