Built for fosters who open their homes and hearts to noenatal, underage, and orphan kittens.
The earliest weeks of a kitten's life are critical—and Foster Kitten helps you get them right. A specialized health tracker for kittens 0–12 weeks, it helps you keep daily logs, spot trends early, share precise reports with your vet, and provide attentive care when it counts.
Tracking
Log daily weights, medications, feedings, symptoms, photos, and clinical notes with fast, intuitive data entry. Snap a photo of your kitten's stool for an instant assessment powered by KittenAI, or log manually. Foster Kitten helps you monitor key indicators—growth, stool quality, and upper respiratory symptoms—so changes don't go unnoticed.
Track socialization as a daily practice across handling, sounds, surfaces, and social experiences. The checklist guides you through what's left to observe each day and preserves your work as you go. Browse a library of care resources and age-appropriate development guides.
By applying veterinary research and established care standards to your data, Foster Kitten highlights when growth and health are on track—and when something may warrant a vet conversation.
Designed for Foster Care
Whether you're caring for your first bottle baby or managing a full litter, Foster Kitten is built for real foster workflows. Track mother cats alongside their litters with queen care tools for nursing, mammary health, and reproductive milestones.
Record the shelter-assigned Animal ID and source organization for each kitten, for unambiguous communication with the rescue. Records stay clear and easy to share—from intake to adoption—supporting collaboration with shelters, rescues, and veterinary teams. With Baby Book, document developmental milestones with photos and narrative text, creating a keepsake that travels with your kitten to their forever home.
Access your data from any device with a browser—at home, at the shelter, or at the vet.

I accidentally found this app searching for a way to organize my kitten foster data…and boy did this deliver!! It is EASY to use, super intuitive, easy to customize for your shelters needs, simple to understand, has great tutorials with video examples. I LOVE having one app to track my current foster kittens and also review my past litters when needed. It’s also a dream to export some of the data and send in to the foster coordinators at the shelter I volunteer for. I also have had wonderful interaction with the app’s creator…so smart and always appreciative of feedback to help improve his awesome program. I am recommending to all fosters I meet!
Developer Response
Thank you so much for your practice of care. It is wonderful to hear that Foster Kitten is helpful. Fosters deserve great tools. I love that the export kitten data feature helps you share health metrics with your care team. I appreciate your guidance and insight. You were among fosters instrumental in the design of the Queen Care feature.
What's New in Version 2.6.0
Foster Kitten's clinical reasoning reads weight entries with more precision, better distinguishing a short-term dip from a genuine downward trend. Where it once leaned on summary judgments, it now tells you what the numbers show.
Foster Kitten now guards against impossible weight entries, such as a weight dated before a kitten's birthday, so your records stay clean and trustworthy.
In-app help has grown throughout the app. Nearly every screen now carries guidance. There is also a new Ask About the App, an assistant you can ask how-to questions in your own words. It points you to where things live and how they work. For anything medical, it will always direct you to your veterinarian or shelter coordinator.
Foster Kitten's Library materials now carry their sources with them. Select materials include a bibliography of the veterinary literature behind them, with tappable links to the original research, so you can read the source material for yourself.
Thank you for your practice of care.
