A cat behavior log is a dated record of what your cat eats, drinks, plays, sleeps and does in the litter box, kept so you can give your vet a clear picture at the appointment. Cats hide illness well and a vet sees your cat for only a short visit, so your notes and short videos from home fill in the rest. A log supports the exam. It does not replace it, and only your vet can diagnose.
Why Home Notes Help at the Vet
Cats are good at masking symptoms. Pain, urinary trouble and kidney problems can build for weeks before an owner notices anything, and a cat that is stressed at the clinic may behave differently from how it does at home. A record of what changed and when helps your vet decide which questions to ask and which tests to run.
Vets commonly ask about appetite, thirst, litter box use and energy when a cat is unwell. Owners who bring dated notes do not have to rely on memory, which is less reliable than most people expect.
What to Record at Home
- Appetite and water: how much your cat eats and drinks compared with usual. Cornell's guide to chronic kidney disease in cats lists increased thirst and urination among the signs to watch.
- Energy and play: whether play, jumping and exploring are normal or reduced.
- Sleep and hiding: new sleeping spots, more time hidden or unusual restlessness at night.
- Movement: limping, stiffness or hesitation before jumping.
- Litter box visits: visits per day, how long each one takes, and whether your cat strains.
- Urine and stool: the number and size of urine clumps, and stool shape and color. A cat fecal score chart gives you shared words to use with your vet, and VCA's page on diarrhea in cats explains what your vet may ask.
- Vomiting and other signs: date, how often and what it looked like.
How to Keep the Log
Note the same things at about the same time each day, write the date on every entry and keep entries short. Use numbers where you can, such as "4 litter box visits" instead of "went a lot." Start a log as soon as you notice a change and keep it going until the appointment.
Save short video clips of anything unusual, such as a limp, a stiff jump or a long litter box visit, along with the date. Our guide on tracking your cat's bathroom behavior gives a simple daily template.
Tools That Make Logging Easier
| Tool | What it records | Good to know |
|---|---|---|
| Notebook or phone notes | Anything you notice and write down | Free, but only covers the times you are home |
| Home behavior camera | Video of how your cat moves, rests and plays in the room | Clips you can show your vet |
| Litter box camera | Visits per cat, visit length, stool shape and color, urine clump events | Builds a baseline for each cat and flags changes |
LitterLens logs each cat's litter box visits and duration, stool shape and color and urine clump events. It builds a baseline in about a week and flags changes from your cat's own normal. Visit count and duration are free to view, and abnormal stool and data alerts need a Care+ subscription.
LitterLens is informational, so your vet decides what a change means. Browse the cat health monitoring collection to see the options.
PawTrack is an indoor camera with auto tracking and a 360° pan. It does not measure health, but its video lets you save a clip of a limp or restless night to show your vet.
What to Bring to the Appointment
- A short timeline: when you first noticed the change and how it has developed
- Your log or a summary of it, with numbers where possible
- Video clips of anything unusual, and a photo of any stool or urine changes if your vet asks
- The food, treats and any medicines your cat currently gets
Our guide on how to share pet health data with your vet covers how to present it, and detecting abnormal cat behavior early lists the changes worth writing down.
When Not to Wait for a Log
Do not spend time building a log in an emergency. Go to a vet immediately if your cat strains in the litter box and passes little or no urine, especially a male cat, if there is no urine for 24 hours or no stool for 48 hours, or if your cat has trouble breathing or collapses. Cornell's page on feline lower urinary tract disease explains why straining is urgent, and our page on a cat that cannot pee or poop lists the emergency signs.
FAQ: Cat Behavior Logs and Your Vet
What should a cat behavior log include?
Appetite, water, energy, sleep, movement, litter box visits, urine and stool, and any vomiting, each with a date. Short entries and simple numbers work best.
Do vets use home logs?
Many do welcome them. Ask your clinic what format it prefers, and bring the notes and clips even if they are rough. Your vet will still examine your cat and decide what tests are needed.
How long should I keep a log before the visit?
Start when you first notice a change and keep it going until the appointment. For a routine check-up, one to two weeks of notes is a good starting point.
Can a camera diagnose my cat?
No. A camera records what your cat does and helps you notice changes. Only a vet can diagnose.
