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.
