Off their food since something changed at home

What this tends to look like

• Reduced intake dating from a specific event: a move, a new pet, visitors, building work, a person leaving
• Eating, but less, and often at odd times or only when the house is quiet
• In cats, eating at night when nobody is about, which is easy to miss entirely
• Sometimes hiding, or eating only in one particular room
• Otherwise well: normal stools, normal energy, no vomiting
• Frequently a multi-pet household where the bowls are close together

What is usually going on

Appetite is one of the first things to drop when animals feel unsettled, and a few days of reduced intake after a genuine household upheaval is a reasonable thing rather than a problem. Cats are markedly more sensitive to it than dogs, and cats are also where the risk sits, because the safe window is short: a cat eating nothing for 24 hours needs veterinary attention regardless of how good the explanation is.

A great deal of this is fixable by changing where and how food is offered rather than what is in the bowl. Cats in particular do badly with bowls in busy corridors, next to a litter box, next to a water bowl, or within sight of another cat. In a multi-cat household, separate feeding stations in different rooms often solve an apparent appetite problem in a day, because the real issue was that one cat was being quietly blocked. Height helps too, since cats prefer to eat where they cannot be approached from behind.

The other useful lever is aroma, not flavor. Warming wet food slightly to around body temperature raises its smell considerably, and smell is what drives appetite in both species. It is worth trying before you buy anything, and it costs nothing. What is worth avoiding is introducing an exciting new food during a stressful period, because if the animal happens to feel unwell around then you can create a lasting aversion to a food you may want later.

What you can do at home

• Move the bowl somewhere quiet and defended, away from the litter box, the water bowl, and other pets
• In a multi-pet house, feed in separate rooms with the doors shut, and see whether intake changes within a day
• Warm wet food slightly. Aroma drives appetite, and this is free
• Keep the routine steady: same times, same place, same food. Predictability helps more than variety here
• Measure what is actually eaten over 24 hours rather than judging by what happens when you are watching
• For cats, count the hours since they last ate properly, and treat 24 hours as a hard limit

What progress should look like

How long to give this before you conclude it is not working.

• First 24 hoursMove the bowl, warm the food, separate the feeding. Cheap changes with a fast effect.
• Two to four daysMost stress-related appetite dips are recovering by here once the environment is sorted.
• One to two weeksBack to a normal intake as the household change becomes routine.
• Beyond two weeksReduced intake lasting that long is no longer a stress response. Get a physical check.

When to stop and call your vet

• A cat that has eaten nothing for 24 hours, whatever the explanation
• Weight loss, or losing muscle over the spine
• Vomiting, diarrhea, or lethargy appearing
• No improvement after two weeks of a settled environment
