I hate that feeling when my cat's distressed after med's, it's so distressing and thinking of you. You're an amazing mum, hang in there.
(Mouse was doing that frothing thing with his L Lysine powder last week but seems better with gel).
How long did your vet prescribe the Metronidazole for? You're not meant to stop antibiotics before the prescribed course (I think because it can cause what ever they are prescribed for to return and be more virulent and resistant to med's). If Cindy's that distressed and there's still quite a bit of time to go on the prescription I'd talking with the vet again. Looking the Metranidazole up on line it also looks like one of the side effects in cats and dogs can be nausea: even more reason to chat with the vet again if there's any chance it's contributing to her feeding issues.
