New Cat Adjustment Tracker (3-3-3 Rule)

Bringing home a new cat and watching it vanish under the bed is unsettling - is this normal settling in, or is something wrong? PetHealthLog lets you log the things that actually tell you: whether your cat is eating, drinking and using the litter box, and the first signs of coming out, exploring and gaining confidence - mapped against the familiar 3-3-3 adjustment timeline. So you can see real progress instead of guessing, and tell a shy cat that just needs time from one that is not eating or drinking and needs a vet. Free, no account, works offline.

Settling in is normal - not eating or toileting is not

Hiding, being quiet and nervous in the first days is expected and usually just needs patience. What is not part of normal adjustment is a cat that is not eating or drinking at all, passes no urine or stool in the litter box, is straining in the box, is vomiting or has diarrhoea, is breathing hard, or seems painful or collapsed. A male cat straining to urinate with little or nothing coming out is a particular emergency. Kittens in particular can go downhill quickly if they stop eating. If any of that is happening, this is not a watch-and-wait situation - contact your vet or an emergency clinic now. This tracker is for following a settling-in cat, not for delaying care when one is clearly unwell.

The 3-3-3 timeline is a yardstick, not a deadline

Many shelters and adoption sources share the same rough framework for a newly adopted cat: the first 3 days are often overwhelming, with lots of hiding; by around 3 weeks most cats begin to settle, learn the routine and explore; and by about 3 months many feel fully at home. It is a general guide, not a rule your cat has to meet - some appear in a day, some take a couple of months, and a shy cat or one with a hard past needs longer. Used as a yardstick, it is reassuring: it lets you see whether your cat is drifting in roughly the right direction.

The trouble is that settling in is easy to misjudge from memory. Did your cat eat last night, or has the bowl been full for two days? Has it come out a little further each evening, or has nothing changed? Is it slowly more relaxed, or quietly more withdrawn? In the worry of a new arrival, a vague "I think she's coming round" is hard to trust, and the basics - eating, drinking, litter box - are exactly what a vet asks about if you do call.

PetHealthLog is free, asks for no account and works offline, so each day you can log whether the basics happened and note the first signs of confidence. The trend is right there, progress is visible, and you have a real record instead of a guess - whether you are reassuring yourself or ringing the vet.

What the new cat adjustment tracker actually does

A settling-in log only helps if it is quick to fill in each day and turns scattered impressions into something you can read. Here is how PetHealthLog handles both.

Signs to ask your vet, rather than keep waiting it out

General guidance from adoption and veterinary sources - when in doubt, call. The tracker helps you spot these, it does not decide them.

  • Not eating or drinking at all, especially a kitten, or no urine or stool in the litter box
  • Straining in the litter box - especially a male cat passing little or nothing - treat as an emergency
  • Vomiting, diarrhoea, breathing changes, or signs of pain
  • Going backwards over time - more withdrawn and less responsive rather than slowly more confident
  • No sign of any progress after about two weeks of patience and a quiet, safe space
  • Any ongoing behaviour worry - best taken to your vet or a certified cat-behaviour consultant

Everyday extras to help a new cat settle

To help a nervous new arrival feel secure, owners often set up a few gentle basics in the quiet room: a cosy covered cat cave or hideaway so it has a safe spot of its own, a calming pheromone diffuser, and an extra litter box and food and water stations close to where it is hiding so the basics are within easy reach. None of these treat an illness or replace a vet exam, and none should be used to put off seeing a vet if a new cat seems unwell - they just help with everyday comfort while your cat finds its feet.

Why "free, offline, no account" matters here

You check on a new cat at odd moments - a glance at the food bowl in the morning, a peek under the bed at night, a flicker of a tail venturing out. The last thing that should stand between you and noting it down is a login screen or a spinning loader.

PetHealthLog stores everything locally on your device. There is no account to create, nothing is uploaded to a server, and there is no tracking. It opens instantly, lets you log the basics or check the trend whether or not you are online, and keeps the data yours. You can export a backup any time and restore it on another phone.

Frequently asked questions

Is this new cat adjustment tracker really free?
Yes. Logging your new cat's eating, drinking and litter box use, noting hiding, exploring and first signs of confidence, following the 3-3-3 settling-in timeline, and the PDF record are all free to use. There is no sign-up and no account, and your cat's records stay on your own device.
What is the 3-3-3 rule for a new cat?
The 3-3-3 rule is a general framework many shelters and adoption sources use to set expectations for a newly adopted cat: roughly the first 3 days a cat often feels overwhelmed and scared and may hide most of the time, around 3 weeks it usually begins to settle, learn the routine and explore more, and by about 3 months many cats feel fully at home and part of the household. It is a rough guide, not a deadline - every cat is different, and a shy cat or one with a difficult past may take longer, from a couple of days to a couple of months. The value of the timeline is as a yardstick: it helps you see whether your cat is gradually making progress in roughly the expected direction, which is far more reassuring than guessing day to day.
How long should I let my new cat hide before worrying?
Adoption and behaviour sources describe early hiding as completely normal - a frightened new cat retreats to a safe spot, and the gentlest approach is to give it a quiet room, familiar scents and time rather than forcing interaction, so its stress eases and it comes out on its own. Some cats appear in a day, others take a couple of weeks. The reassuring signs are that even while hiding the cat is eating, drinking and using the litter box, usually overnight when the house is quiet. Many sources suggest that if there is no sign of any progress over about two weeks, or the cat is not eating, drinking or toileting, it is worth asking your vet or a certified cat-behaviour consultant for help. The tracker is built around exactly that distinction: it makes it easy to see whether the basics are happening and whether confidence is slowly building.
How do I know my new cat is settling in, not unwell?
A settling cat tends to show slow, steady progress: still hiding but eating and drinking, then venturing out more, exploring at night, using the litter box normally, and gradually responding to you. What is different from ordinary adjustment is a cat that stops eating or drinking entirely, has no urine or stool in the litter box, is vomiting or has diarrhoea, is breathing hard, seems painful, or goes backwards - more withdrawn and less responsive over time rather than slowly more confident. Because a quiet, hiding new cat and a quietly unwell new cat can look similar at first, the most useful thing you can do is record the basics each day, so you can see whether the picture is improving or not. The tracker keeps that record, but only a vet can confirm whether a cat is healthy.
Does it work without an internet connection?
Yes. PetHealthLog is a progressive web app that works offline. Once it has loaded you can log whether your new cat ate, drank and used the litter box, note hiding or a first exploration, or check the trend without a connection, so logging it each day never depends on having a signal.
Is this a substitute for veterinary advice?
No. PetHealthLog is a record-keeping tool, not veterinary or behaviour advice. It does not diagnose anything, decide whether your cat is simply shy or unwell, or set a timeline your cat must meet. The 3-3-3 rule is a general guide, not a promise. Whether your new cat needs to be seen - especially if it is not eating, drinking or using the litter box, or seems unwell - is a decision for a licensed veterinarian, and ongoing behaviour worries are best taken to your vet or a certified cat-behaviour consultant. The tracker simply helps you keep an honest record of how settling in is going.
