I'm glad the test was negative. Did they get any other possible answers as to why she did what she did?
I'm not always the one who has to have all of the answers. With what I observed, and they agreed, probably some kind of brain vascular accident.
If you want to read the details, then continue: (I sleep very strange hours) and it was already I think about the get light, when the baby bunnies and birds start up. I wasn't quite asleep and heard a "chattering" for just a moment...but she was under the covers. (Not in the window). It looked like one eye was slightly more dialated. With her age and all and that she seemed comfortable, I let things be. Checked on her often but not to disturb her (as kitties usually if not well like their private space if feeling badly and this was hers). Soon she was still meowing a little when I'd check on her, but felt so limp.
I called the doc in the AM and said I thought she was passing...but if worries later, could I sneak her in (if PTS was necessary). She'd gotten so quiet and limp, I thought it was just a matter of time.
I put out her favorite food, just in case...and soon she got up and ate, drank. But she couldn't walk right...crossing her feet, stopping, clearly looking lost, not able to jump at times and yet at others.
I knew she wanted on my lap but couldn't jump and reached down and she bit me...not her usual TORTIE bites. She was confused.
I took her in. Because of the symptoms (and skin break on me) we had to do the rabies thingie (is it a necropsy?) She seemed fine some of the time but I knew she couldn't carry on that way. I was okay with letting her go.
I didn't have a full necropsy done...she was 15+ and...stuff happens. In my mind, that's enough sometimes for my conscience. It can be one's time to go. She'd not have been happy long and she still had her favorite meal (TUNA) and got to watch the birdies out of the window before she left me. Sounds like a kitty heaven on Earth in that last hour or two.
We did agree it sounded like a stroke or something.
She had been slowing down a bit but her bloodwork had been super for a kitty with early kidney disease.
What more can you ask for, eh?
