So the vet’s opinion is that Maya has been entirely too lethargic — and, more worrisome, not eating enough. Essentially: she may be anorexic. After puking nonstop for a week, she ended up with no real volition to eat, is the hypothesis. She’s gotten pretty gaunt in the meantime.
So Maya’s now getting Valium. You heard right: apparently one of its side effects in cats is that it acts as a strong appetite stimulant. Half an hour after getting the pill (oh fun), she’s actually interested in eating. And, more to the point, eats. Assist-feeding of the high-calorie cat food still continues, but hopefully she’ll get enough nourishment that she’ll stop looking so frail and listless.
Getting her back to her active self is going to take a while.
