Fostering with CatNap from the Heart? FANTASTIC! Thank you for your assistance! Your fostering experience can last anywhere from 2 weeks to several months depending on the age and needs of the litter. We use Iams Kitten or Cat Dry Food (purple and orange bags) and a variety of wet food (chicken or turkey is easiest on the young systems of kittens). Water and dry food should always be available for kittens and cats (dry starts at 4-5 weeks for kittens). Wet food is generally provided several times a day for kittens (their tummies are small) and once a day for the adults. Lots of attention, love, and socialization is the key! We are here to help, so please review the following pages for info and reach out with any questions!
