Catbox
One care log, one weight chart and one vet calendar per cat — for a whole household
Built for homes with more than one cat. Give each animal a profile, log a feed, litter change, medication, vet visit, weigh-in or groom in two taps, watch the weight line for a downward drift, and keep vaccine and checkup dates from slipping. Free, offline, nothing to install.

What you can do in Catbox on the web
A profile per cat
Name, breed and birthdate — Catbox works out their age — with their own colour, initial avatar and separate care record.
Two-tap care logging
Feeding, litter change, medication, vet visit, weight log, grooming or other, with a date, time and note, straight from the Today card.
Weight trend chart
Every weigh-in on one line chart per cat, with the change since the last one and a steady/up/down verdict so you spot a drift before the appointment.
Vet and vaccine reminders
Vaccine, checkup, medication refill, dental, grooming or other, each with a due date and an overdue, due-today or due-in-N-days state — per cat and across the household.
A Today screen for the household
Each cat's card shows what has been logged today, how many reminders are overdue, and the four quick-log buttons you use most.
Completely private
Everything stays in this browser — export the household as JSON, or the care log as a CSV to hand your vet.

Questions
Is the web version of Catbox free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Catbox iPhone app?+
The iPhone app fires a real local notification when a vaccine or checkup falls due; on the web a reminder only turns red when you open the page. Cat photos from the phone app are not part of the web version — each cat gets a coloured initial avatar instead. Data lives in this browser only: it does not sync with the iPhone app, and clearing site data erases it, so export a backup if it matters.
