how old does a kitten have to be for dewormer
Typical Deworming Cycle. The U.S. Centers for Disease Control and Prevention recommends kitten deworming at 3, 5, 7 and 9 weeks of age to prevent infestations from taking hold. However, many vets wait until kittens are 6 weeks old to start the deworming cycle and then follow a schedule of two subsequent deworming sessions at 9 and 10 weeks of age.
