Cat Not Eating: What to Do

A cat who stops eating is always a concern. Unlike dogs who may skip meals without consequence, cats who don’t eat for more than 24–48 hours risk a serious condition called hepatic lipidosis (fatty liver disease).

Common Reasons Cats Stop Eating

• Stress: Changes in environment, routine, or household (see anxiety guide)

• Dental pain: Broken teeth, gum disease, or oral lesions

• Nausea: From illness, medication, or dietary issues

• Illness: Kidney disease, infections, digestive problems

• Food preferences: Sudden pickiness (sometimes caused by stale food or temperature)

• Recent vaccination: Temporary appetite loss is common after shots

What to Try at Home

• Warm the food slightly to enhance aroma

• Try a different protein or texture

• Offer food in a quiet, low-stress location

• Add a small amount of low-sodium broth for flavor

• Remove and replace food if it’s been sitting out (cats prefer freshness)

When It’s an Emergency

See your vet if your cat hasn’t eaten for 24+ hours, especially if accompanied by vomiting, lethargy, or weight loss. Overweight cats are at higher risk for hepatic lipidosis. Our Feeding Guide has more on healthy eating habits.
