Determining the Age of Your Orphan Kitten

You’ve rescued an adorable little fluff ball. Before you can decide what you need to do next, you need to determine his age. A one-week old kitten needs a completely different level of care than a four week old. Once you know his age, you’ll know if you need to stimulate him to potty or provide a litter box.
