Can I withhold rent due to a mouse infestation?

Question Details: My landlord said he is going to file to evict me tomorrow if I don't give him half of rent. I have told him multiple times that there is a mouse infestation in the apartment and I can't have it. I have a 5 month old whojust started crawling. I have seen them on my counter all over my apartment and now in my stove. I took the burners out and there was mouse feces under all the burners. I've been told out could be dangerous for my child and I if I were to cook on the stove because of toxins that are released. I need to know what my rights are. Important Notice
