How an 8-pound body handles trace salt
One crumb's worth of salt is measured in granules, not grams — we're talking maybe 5-10 individual salt crystals here. Your cat's kidneys can easily process this minuscule amount without strain. For context, she'd need to ingest about 1/4 teaspoon of pure salt to reach concerning levels, which would require eating half a heavily seasoned tortilla.
The salt might make her drink more water temporarily, which is actually protective. Watch the water bowl for unusually frequent visits, but don't restrict access. What you don't want to see is neurological signs like stumbling or seizures, which would indicate true salt poisoning — extremely unlikely from this exposure.
The crumb vs. the counter: what really happened
When cats 'lick' a crumb, they're often just moving it with their tongue rather than ingesting the entire particle. The rough tongue surface may have scraped off some salt while leaving most of the tortilla material behind. This is why the risk is lower than if she'd deliberately eaten a piece.
Check where the crumb was: if it sat near raw meat juices or cleaning products, those pose greater risks than the tortilla itself. Assuming it was just a fallen food scrap, the main concern would be whether this becomes a habit. Cats who learn counters yield treats may progress to dangerous foods like onions or chocolate.
Why drooling tells more than vomiting here
Excessive salt can irritate a cat's mouth before it ever reaches the stomach. If you notice sudden drooling or lip-licking, it's likely her mouth reacting to the salty taste rather than systemic illness. Offer fresh water to rinse her mouth, but don't force it.
Vomiting, if it occurs, will probably happen within 2-4 hours as her body rejects the unfamiliar salt concentration. One episode isn't concerning unless she appears distressed during it or can't settle afterward. Continuous retching or producing nothing but foam means you should call the vet, as dehydration becomes a risk for smaller cats.
The 12-hour observation window for subtle changes
While acute poisoning isn't a concern, subtle shifts in behavior can indicate mild discomfort. Note whether she's sleeping more than usual or avoiding bright lights — signs of a minor headache from salt intake. These should resolve with rest and hydration.
By tomorrow, if she's maintaining normal routines — using the litter box, grooming, and seeking attention — you can consider the incident closed. Should she develop watery diarrhea or show disinterest in food beyond one meal, a vet visit would rule out coincidental issues like intestinal parasites flaring up after dietary irritation.
