Hello I have a kitten who is 4 months old now I treated her for worms about a month ago because I noticed little worms on her butt and it said to give the dewormer again after two weeks so I did that. And that was about 2 weeks ago and I noticed the worms again a few days ago and again today So idk if the dewormer I used isn’t strong enough or what I should do.

You are probably giving the wrong dewormer. It sounds like you need to be treating for tapeworms and most general dewormers do not treat those. I suggest you give her a dewormer for tapeworms and repeat after 3 weeks. Also, you need to treat her for fleas as that is how they get tapeworms.
