FragileKitten in detail β what it tracks, how it keeps a team in sync, and why a fading kitten shows up early. (Tap any screenshot to enlarge.)
Every weigh-in is plotted against the 25thβ75th percentile band for the kitten's age (from the PLOS ONE 2022 kitten growth standard), with the median and the expected weaning/weaned ages marked. A kitten drifting below the band shows up at a glance β long before it's an emergency.
Each day's feedings stack into one bar, one block per feeding, with a dashed tick for the expected formula at that weight and age. Underneath, the rollup: latest, average and range. Actual intake sits right next to what a kitten that size should be taking.
One quick sheet for a weigh-in, feeding, toileting, note or treatment β backdate it if you're catching up, jot what you observed, and attach a photo or video right there. Leave the feeding amount blank and it's auto-derived from the weight change.
Photos and videos live on each kitten, alongside the notes and numbers. Invite your vet with a Vet role and they see exactly what you saw β the rash, the wobble, the weight trend β without a single forwarded text or lost photo.
Invite a co-foster, a coordinator, a vet or an auditor by email β each with the roles that decide what they can do (Admin, Supervisor, Caregiver, Vet, Auditor). It's a single-use invite tied to their address, and you can change or revoke access any time. Division of responsibility, without the group-text chaos.
Not a stripped-down companion app β the entire tool works in your phone's browser. Log the 3 a.m. feed, snap a photo, check what's due, scrub the calendar β right from the kitten's side, half-asleep, one-handed.





The home screen greets you with what matters now: a med due, who's still in quarantine and for how long, and a live timeline of today's feedings, weigh-ins and photos across your whole caseload.
Every checkup, feed, weigh-in and treatment laid out by day β scrub back through a kitten's entire stay, in their timezone, even the entries your co-foster logged from two states away.
Your whole caseload on one screen β litters grouped, ages and days-in-care up front β and a star for the ones you're watching closest so they're always on your home screen.
Every change is recorded β an audit trail of who entered or edited each checkup. When a team is sharing care, there's always a trustworthy record of exactly what happened.
Start from your existing records and export everything to Excel whenever you like. No lock-in β it's your caseload, your data, on your terms.
