Tabby cat looking at a food bowl—guide to appetite loss and dehydration
If your cat won’t eat or drink, timing matters: what’s safe to try at home—and when it’s time to call the vet.

When a cat skips a meal, we all want to believe it’s “just a mood.” Sometimes it is. But when your cat isn’t eating and isn’t drinking, you’re right to take it seriously—especially if they’re hiding, vomiting, or acting “not themselves.”

This guide is the way I think through it at home: quick rule-outs first, then gentle steps for the first 24 hours, then what changes after 24 hours. I’ll also show you the red flags that mean you should call your vet now (no waiting, no guessing).

Personal note: the biggest mistake I made early on was assuming my cat was “being picky” when he was actually stressed and slightly dehydrated. Once I started tracking the basics (food, water, litter box, energy), the pattern became obvious—and the fix was much simpler than I expected.

1) First, quick rule-outs (5 minutes)

Before you change food brands or panic-buy toppers, do these quick checks. They solve a surprising number of “mystery” refusals.

  • Check the basics: old/dirty bowls, stale water, food that smells “off,” or a bowl in a busy spot.
  • Environment shifts: visitors, loud noise, construction, a moved litter box, or a new scent (cleaners, perfumes) can shut appetite down.
  • Recent food change: new brand/flavor/texture? If you can, offer the previous food again and transition slowly later.
  • Pain clue scan: limping, drooling, pawing at mouth, hiding, tense belly, hunching, or “don’t touch me” behavior.
  • Litter box check: are they peeing and pooping normally? Straining or frequent trips matters a lot (more below).

2) Hours 0–24: Gentle at-home steps

Goal for the first day: reduce stress + offer easy wins (smell, warmth, quiet) while you watch hydration and the litter box closely.
  • Fresh water in two places: one near the usual spot, one in a quiet corner. Try a wide ceramic dish or a fountain.
  • Warm wet food slightly: 10–15 seconds (just warm, not hot). Stronger smell often flips the “eating switch.”
  • Offer small, frequent plates: teaspoons or small bites. Big bowls can be overwhelming when a cat feels off.
  • Make the room calm: lights softer, voices low, no crowding, no hovering over the bowl.
  • Write down what you see: food offered, how much eaten, sips of water, energy, and litter box trips.
  • If you can, weigh your cat: even one number helps you spot rapid change.

3) Hours 24–48: What to try next

After 24 hours, the bar gets lower for “let’s wait.” Cats can get into trouble if they stop eating for too long, especially if they’re overweight, senior, or have underlying disease.

  • Offer two textures: pâté and chunks/gravy. Give a teaspoon taste test, not a whole serving.
  • Try two proteins: chicken/turkey and a fish option (short-term). Some cats reject a protein, not the whole brand.
  • Warm + moist: add a spoon of warm water to wet food to create a stew.
  • Comfort matters: a quiet warm resting spot can help stressed cats feel safe enough to eat.
  • If appetite stays low after 24 hours: call your veterinarian. Don’t try to “outsmart” a sick cat with endless toppers.
  • Diabetic, senior, underweight, or chronically ill cats: don’t wait—call earlier.
Why vets take this seriously: cats that don’t eat for prolonged periods can develop hepatic lipidosis (fatty liver), which can become serious. If your cat is truly not eating, getting professional guidance early is safer than waiting.

4) Warning signs: Call the vet now

Red flags mean “call now,” not “wait until tomorrow.”
  • No food for more than 24 hours (or your cat is eating almost nothing).
  • No water for 12–24 hours, especially with other symptoms.
  • Repeated vomiting, blood in stool/urine, or black/tarry stool.
  • Trouble breathing, collapse, severe lethargy, or profound weakness.
  • Urinary signs: straining, frequent trips, crying in the box, or little/no urine (urgent—especially males).
  • Yellow gums/eyes, fever, or sudden dramatic weight loss.

5) Hydration checks & easy fixes

These checks aren’t a diagnosis—but they can help you judge urgency while you contact your vet.

Quick at-home checks

  • Skin tent: gently lift skin over the shoulders and release. Slow return can suggest dehydration.
  • Gums: moist and pink is normal. Dry/tacky or pale gums are concerning.
  • Energy: “flat,” hiding, or unusually quiet plus low water intake = take seriously.

Easy hydration fixes that are usually safe

  • Multiple water stations in quiet spots (not next to litter, not next to loud appliances).
  • Wide bowls and daily washing.
  • Wet food “stew”: add a spoon of warm water and mix.
  • Cat-safe broth: plain chicken/turkey broth with no onion/garlic/leeks/spices.

6) Safe appetite boosters

These are gentle nudges, not “hacks.” If your cat seems sick, focus on vet guidance rather than experiments.

  • Smell first: warm wet food slightly; offer a teaspoon taste test.
  • Texture test: pâté vs gravy/chunks. Some cats refuse texture, not food.
  • Small plates: tiny portions reduce pressure and waste.
  • Calm ritual: quiet room, predictable routine, no hovering over the bowl.
  • Ask your vet about medically prescribed appetite support if refusal continues.
Avoid: salt tricks, essential oils, human medications, or force-feeding without veterinary guidance.

7) What not to do

  • Don’t force-feed or syringe-feed without veterinary guidance (aspiration risk + stress).
  • Don’t give human meds, essential oils, garlic, or onion—these can be dangerous for cats.
  • Don’t switch foods repeatedly in one day. It often backfires.
  • Don’t ignore the litter box. Peeing problems can become emergencies fast.

8) FAQ

How long is too long for a cat to go without eating?

More than 24 hours is concerning. Call your vet sooner if your cat is senior, diabetic, underweight, very overweight, or acting ill.

What if my cat isn’t drinking?

Try fresh bowls in quiet spots, a fountain, and adding warm water to wet food. No drinking for 12–24 hours plus other symptoms → call the vet.

Can stress alone stop appetite?

Yes. Moves, visitors, loud sounds, or a new pet can do it. Calm routine + tiny “taste tests” can help unless other red flags are present.

Should I give tuna water?

A teaspoon of unsalted tuna water can tempt appetite short-term. Don’t rely on it long-term, and don’t add salt.

Should I change food brands immediately?

If this started after a sudden food change, offering the old food again may help. Otherwise avoid frantic switching—track symptoms and call your vet if it lasts.
