So i have known this person for 2 years and i go over to there house every friday to hang out with her brother she has lots of animals outside that are pretty clean but she also has alot in her room and those ones cages are filthy 90% of the time. Her room smells very bad.I am not just worried about the health of the animals but also the health of her.I dont think talking to her about it in person would be very good cause she would problably get mad and defensive.Maybe an anonymous letter?Just not sure how to tell her.
