So this past week we trapped two feral kittens, one on tue and her sister on Wednesday. Today was their first vet visit. They are healthy, only 8-9 weeks and only 1.8 lbs. they each have a few fleas, not horrible but they have them. They do have worms, but this past weekend I had brought fecal sample in and received the meds so treated them sat, sun and mon, and will repeat in three weeks. For the fleas Vet and staff recommended frontline plus, which I have always been hinky about using any of those types of meds but I bought it there and have it home. Anyone have experience using this on kittens? Would like some opinions and input. They said it's ok to apply now, or wait a week after they spend another week eating good...thoughts? We named them Maggie Mae and Rosie. Maggie is the darker closest one.
