Remember wait till the potty spot has a smell to it before adding the potty area in. Once the bowl or other potty spot thing has sat a couple days with the potty in it then change it out. If the hamster moves to a different spot then move the potty area there.

My Matilda was potty trained when I got her but now she uses her wheel and her house as her potty. Don't know why? I have tried but she refuses to use her potty. She has also got into the habit of bottle chewing which I am trying to discourage. She is just soaking herself from chewing and she is very distructive. Lol
