Foster kittens through the most fragile weeks. Track weight, stool, and feeding daily against clinical standards, and share clear reports with your vet.
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, including 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 to create a keepsake that travels with your kitten to their forever home.

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.
Thank you!

This is my first time fostering and first time “having” a cat. This app has been such a huge help as I navigate their growth, track their feedings, and battle sleep deprivation as I try to help these four little newborns thrive. Thank you so much!!
What’s New in Version 3.0.0
Audio Logging
Record weight, feeding, and stool entries by voice when your hands are full—because they usually are. Tap the mic and say, “Whiskers, weight 188 grams, entry complete.” The Basic Plan includes up to 4 audio entries per day; Pro includes up to 75.
Procedures
Schedule and record general procedures—including checkups, dental care, and surgeries—in addition to vaccinations and spay/neuter procedures.
Reminders
Set reminders for vaccinations, spay/neuter appointments, and general procedures.
Scheduled Appointments
View and manage every upcoming appointment from one dedicated screen.
Weight
Weight assessment now focuses on each kitten’s individual rate of gain. We’ve removed comparisons to age-based averages because healthy size and growth can vary widely among kittens of the same age.
Clinics and Shelters
Large rosters—even those containing hundreds of kittens—now load and filter quickly for shelters and clinics using Foster Kitten.
Performance
High-resolution medical photos are now processed in the background, keeping the app responsive while they save.
Foster Kitten helps you maintain organized records, view kitten data in the context of relevant care standards, visualize trends over time, and prepare for clearer, better-informed conversations with veterinarians.
