Foster Kitten helps caregivers track kitten health, make more informed care decisions, and communicate more effectively with veterinarians during the first 12 weeks of life, when kittens are at their most fragile. Tracking Log daily weights, feedings, symptoms, mediations, photos, and clinical notes with fast, intuitive data entry. When your hands are full, use hands-free voice logging to record weights, feedings, and stool observations. 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.
