I just wanted to thank you for the rating and bonus; they're greatly appreciated.
Metronidazole has a very foul taste to it which makes it really difficult to dose in cats unless it's compounded by a special pharmacy into tasty treats or possibly a gel which can be rubbed in the ear. But it sounds like you've worked it out:)
I do understand how it may be difficult to have this sort of conversation with your vet but at this point, they should be suggesting alternative explanations to you...or at least this is the way I see it. And, most savvy owners will research their pet's symptoms so I'm never surprised when alternative suggestions are made. Some I agree with and some I don't but I always explain why.
I'll also look forward to an update in a few days. Kind regards, Deb
