She seems perfectly normal and herself now. Moving and acting normally, looking normal and happy. Lasted just a few minutes. Didn’t seem upset about it this time, just came up close and sat down. I was way more upset about it that she was.

Not sure if a scratch could have done it but I do feel that SOMETHING hurts when he tries to get it off the floor.

Hm, something is going on there; I’d still suspect pain of sorts. I’d have him checked. Sometimes things start out subtle.

Was it some new food item by chance? Is it still happening? Did you try with different foods/treats?

Any other abnormalities with head movement? Any signs of pain?

Surely you must have a veterinary ER or 24-hour hospital or an on-call vet somewhere? These are SERIOUS symptoms.

No further funny discharge last 48 hours. Going in for semi-annual soon, so I’ll bring it up; as well as see the vet sooner if repeats. Strange, though…

What would make it smell that way? Only those two times, otherwise it looks and smells fine.

Yes, will be watching carefully. The first time I just found the “splat” and it was no telling where, who or what it came from. I’m assuming probably vagina but not sure (the second time I found it was on her bedding. She doesn’t lick anywhere excessively, there are no changes in drinking or urination, no other signs I can see. Once she left a tiny poop on the bed; found that in the morning, kind of surprised me. It was a tiny grumple and it never happened again. Doesn’t have diarrhea or mucous or anything wrong with the stools either. Had one little regurg few days back but it was normal in color and happened only once. No strange smells coming from her anywhere. No scratching, no head shaking other than what I’d consider normal.

It’s particularly the vinegar-like smell that really confuses me. WHAT smells like vinegar?

Vomiting and stumbling indeed means a very sick pet. There is one thing to do – see a vet. By the sound of it, see a vet immediately.
