Cats hide illness better than any other domestic species. By the time a cat owner notices something's wrong, the cat is often hours away from a serious emergency. This guide covers the cat-specific emergencies that are easy to miss, where to go in Calgary at 2am, and what an ER visit actually costs.
Cat-Specific Emergencies (Easy to Miss)
Urinary blockage (male cats — #1 cat emergency)
Male cats have a narrow urethra that can get blocked by crystals, mucus, or stones. Signs: straining in the litter box producing little or nothing, crying out in pain, vomiting, hiding, lethargy. Fatal in 24–72 hours if untreated due to kidney failure and bladder rupture. Don't wait. ER now. Female cats can block too but it's much rarer.
Linear foreign body (string/ribbon/floss/tinsel)
String saws through the intestines as the gut tries to move it through, causing fatal perforation. Never pull visible string from the mouth or anus. Go to ER. Common holiday emergency: tinsel and ribbon from gifts.
Lily ingestion
All true lilies (Easter lily, tiger lily, day lily, Asiatic lily) are highly toxic to cats. Even chewing a leaf, drinking the water from a vase, or grooming pollen off their fur can cause acute kidney failure. ER immediately, even if the cat seems fine. Don't bring lilies into homes with cats. Period.
Saddle thrombus (aortic thromboembolism)
Sudden hindlimb paralysis caused by a blood clot from undiagnosed heart disease. The cat will be screaming in pain, hindlimbs cold and limp. ER immediately. Often the first sign of underlying heart disease.
Hepatic lipidosis (fatty liver)
Cats that go 24–48 hours without eating — for any reason — can develop fatal liver disease. Overweight cats are at highest risk. If your cat hasn't eaten in 36+ hours, go to the ER, even if no other obvious symptoms.
Tylenol / acetaminophen poisoning
One tablet can kill a cat. Cats lack the liver enzyme to process acetaminophen. Symptoms appear in hours: lethargy, brown gums, vomiting. ER immediately. Same applies to ibuprofen, aspirin, and naproxen — all highly toxic to cats.
