Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. You can definitely deworm Fiber now. For a kitten this young, you can use Pyrantal pamoate which is available over the counter. The bottle will have all the details as to how much to give. I would recommend repeating this in 2 weeks. Take care. Fiber is such a cutie!
