That’s great to hear that she’s taken the tissue! What your doing with the treats is great and I would keep at it. She’ll get that your not a threat soon enough.
First of all, Kilo is absolutely gorgeous! What cage do you have? I would add more substrate so she can burrow. Hamsters love to make burrows to store food, sleep in, etc. The best you can go for is 6 or 7 in. and 4 at the minimum.
You can also add more to do. I love how you added the cardboard tubes, hamsters always seem to love thoses. I would also advice to make a ramp down the platform. Just to make sure she doesn’t jump and hurt herself. You can also add an empty tissue box to the cage too. It makes a great cheap hideout and there is cardboard to shred aswell! What size is your wheel? I’m sure others will be able to give better advice too!
