Kitten Age Chart

"How old is this kitten?" is one of the first — and most important — questions every rescuer and foster caregiver has to answer. A kitten's age determines everything: whether they need bottle-feeding, when to start weaning and litter training, and when they're ready for vaccines, spay/neuter, and adoption.

This free, printable chart from the Esther Neonatal Kitten Alliance makes it easy. Use simple physical cues — weight, eyes, ears, teeth, and mobility — to estimate any kitten's age from newborn to 8 weeks, and know exactly what care each stage needs.
