Of course it is an annoying for you.Its her pet and she should be taking care of it.She can ask for your help once in a while.I had a different situation with my pet. I had a puppy and enjoyed training her.My mom intentionally tried to turn it into spoiled brat.I tried to potty train her.My mom encouraged it to soil my bed or sofa.My dog eventually developed Dr Jekyll and Mr Hyde personality. She would be a brat in my absence and most adorable and well behaved in my presence.
