I want this to be a complete guide for caring for a kitten week by week. If you find a kitten, you want to try your hardest to keep with them with their mothers. Their mothers will be able to nurse them, keep them warm, and protect them. Mothers know how to care for their babies so if they can be left with their mothers, they should for at least 8 weeks.
Ever think about fostering a cat? Listen to my story about fostering my first cat and see the true and raw emotions that go on through each of the steps of the fostering process. I wish I had something like this when I first started fostering.
