I have a 19 year old tabby cat (female, spayed, had one litter prior).

Late Tuesday night, she began exhibiting very pronounced dizziness and listing to her right. I immediately took her to the emergency vet and, after examination, it was determined she has vestibular disease. Given the debris/gunk they observed in her ear she was prescribed amox/clav oral suspension 2x for 7 days and meclizine 1x a day.

She slept most of the day after this occurred (I assume due to the stress of the vet and her age) and showed immediate improvement with only the antibiotics (meclizine was in transit from Amazon).

For two days she was back to normal and then yesterday she started showing dizziness again and it has continued into today. For the first time since this started she defecated on herself due to trouble getting into/staying in the litter box (shallow walls, clean).

Is it normal for the symptoms to be intermittent? How we can I help with the litter box situation? I've started the meclizine now and it doesn't seem to do much at all at 12.5mg once a day.

To try and head off any other questions:

-She is strictly indoor, eats quality cat food, and has had no issues with eating/drinking/litter usage prior to this.

-Very unlikely she got into something or there are toxic fumes, etc. as we have 3 other cats (all eat the same diet) and a dog, so we are very cautious to pick up any dropped meds, food, even thread/string as we know their danger as well.
