Cats are not just small dogs when it comes to appetite loss — a cat that stops eating faces a specific, serious risk that makes this symptom more urgent than it might seem.
Why This Is More Urgent in Cats
Cats that don't eat for an extended period are at risk of a condition called hepatic lipidosis (fatty liver disease), where the body mobilizes fat too quickly and overwhelms the liver — this can happen within just a few days of reduced eating, especially in overweight cats.
The 24-Hour Rule
A cat that hasn't eaten anything in 24 hours should be seen by a vet — this is a shorter window than most owners assume, precisely because of the liver risk described above.
What Might Be Behind It
Dental pain, nausea, stress, respiratory infection affecting smell (which drives appetite in cats), or systemic illness can all cause appetite loss. The cause needs identifying, not just managing symptomatically.
What Not to Do
Don't wait it out hoping your cat will eat when hungry enough — cats don't reliably self-correct this the way some other species might, and the liver risk means time matters.
Frequently Asked Questions
My cat is still drinking water but not eating — is that better?
It's a positive sign for hydration but doesn't eliminate the appetite-loss risk. Still see a vet within 24 hours.
Are overweight cats at higher risk?
Yes, significantly — hepatic lipidosis risk is elevated in overweight cats that stop eating.
Can stress alone explain a cat not eating?
It can cause short-term appetite loss, but the 24-hour rule still applies regardless of suspected cause.
Should I try tempting foods before calling the vet?
You can offer a favorite food, but don't let that delay a vet visit if 24 hours has passed without genuine eating.
