A cat who eats like clockwork for you can turn into a cat who won't touch the bowl for a sitter — not because anything's wrong, but because a change in who's doing the feeding is exactly the kind of disruption that puts a cat off their food. It's one of the most common messages a sitter sends mid-stay, and one of the most avoidable with the right handover.
The short answer
A cat skipping a meal or two for a new person is common and usually not urgent. What actually matters is the specific setup that gets them eating again quickly, and knowing the point at which normal fussiness becomes a reason to call the vet — which for cats specifically, is sooner than most owners think.
Why this happens
A change in caretaker is a well-recognised trigger for temporary appetite loss in cats, alongside things like a disrupted feeding schedule or unfamiliar smells around the food area. It's not usually about the food itself — it's the whole context around eating that's changed, and cats are particular about context in a way dogs generally aren't.
What actually helps
- Keep the exact routine, not just the exact food. Same bowl, same spot, same rough time — changing any one of these on top of a new person is one disruption too many for some cats.
- Leave the room, or stay well back. Many cats won't eat while being watched by someone unfamiliar. A sitter placing the food and stepping away, checking back later rather than hovering, often solves it on its own.
- Warm wet food slightly, or add a small amount of warm water or broth if your cat's normally on wet food — this increases the smell, which matters more to a stressed cat's appetite than the taste does.
- Don't switch foods to try to tempt them. It's tempting to offer something more exciting when a cat's not eating, but a food change on top of a stressful moment is another disruption, not a fix. Stick with what they know.
- Multiple small offerings rather than one large one, if your cat's the type to graze rather than eat in one sitting — a sitter who assumes one skipped bowl means "not eating" may not realise this is just how your cat normally does it.
What's normal versus what's a vet call
This is the part worth being precise about, because the window is shorter than most people assume.
Generally fine, with the steps above:
- Skipping one meal, or eating noticeably less than usual, in the first day
- Eating once the sitter's left the room or gone quiet
- Returning to normal within 24 hours
Time to call a vet:
- No eating at all for more than 24 hours — this is the point vets consistently point to, not "a couple of days," because cats can develop a serious liver condition from prolonged fasting far faster than dogs can
- Not drinking water either, alongside not eating
- Any additional signs — vomiting, lethargy, hiding beyond their normal settling-in pattern, or visible discomfort
The 24-hour mark matters more for cats than the "give it a few days" instinct most owners have, so it's worth stating explicitly in your handover rather than assuming a sitter knows the timeline.
What to actually tell your sitter
- Your cat's exact feeding routine — bowl, spot, timing, and whether they graze or eat in one sitting
- Whether they're known to skip meals around new people, and how long that's lasted in the past
- The specific point at which you want a call — most owners land on "hasn't eaten by [time] tomorrow," which is more useful to a sitter than "let me know if she's not eating"
- Anything that's helped in the past — warming food, a particular flavour, privacy while eating
Why this is worth writing down before it happens
A sitter checking a bowl at 9pm and seeing it untouched has no way to know if that's day one of normal settling-in or something that's been going on since yesterday, unless the timeline and the threshold are written down in advance. That single piece of context is what turns a stressful guessing game into a simple check.
Quirks & All keeps your cat's normal eating pattern and your specific "call me if" threshold on their profile, so a sitter isn't deciding in the moment whether an untouched bowl is worth worrying about.
