Why drooling means immediate action for a 6 kg cat
The drooling you're seeing isn't just irritation—it's a sign of chemical burns in her mouth from the de-icing salt. These products contain concentrated chlorides that damage tissue on contact, and her small body size makes even tiny amounts dangerous. Right now, her saliva is trying to dilute the salt, but this also risks pulling fluid from her bloodstream.
Don't offer water yet, as sudden fluid intake could trigger dangerous sodium shifts. Instead, wipe her gums gently with a soft, damp cloth to remove residue while someone calls the emergency vet. Time matters: salt poisoning can cause seizures within hours if untreated.
How soup makes this exposure different
Liquid exposure is worse than dry salt because the dissolved crystals coat more surface area in her mouth and throat. The warm soup likely helped the salt absorb faster into her tissues compared to licking granules. Watch for pawing at her face or repeated swallowing—these suggest throat burns developing.
The fact she only licked (rather than drank) the soup buys some time, but don't wait for vomiting or lethargy. Cats hide pain well; that visible drooling means she's already in significant discomfort. Transport her in a carrier lined with towels in case of tremors.
The critical first two hours after ingestion
Emergency vets will likely give IV fluids very slowly to correct her sodium levels without shocking her system. They may rinse her mouth under sedation to prevent further damage. Blood tests will check for hypernatremia (salt poisoning), which can alter brain function at this small body weight.
Bring the ice melt container or note its brand—some contain extra toxins like ethylene glycol. If she develops muscle twitches or seems disoriented during transport, keep her in dim light and avoid sudden noises, as neurological signs worsen with stimulation.
Longer-term risks even after treatment
Even if she seems better after fluids, demand follow-up bloodwork in 24 hours. Salt poisoning sometimes causes delayed kidney strain as her body tries to excrete the excess sodium. You may notice increased urination or litter box avoidance as aftermath.
Prevent future exposure by using pet-safe ice melts and never repurposing food containers for de-icing. Cats are drawn to salty tastes but lack the physiology to handle these compounds. A single lick caused this reaction—imagine if she'd eaten more.
