Hamster houses on wheels

Dad has created all these trolleys so that the hamsters' houses in the form of plastic containers can be easily wheeled around. So cool, right? :>
During the day, some will be wheeled to my bedroom as it is cooler.

I'm glad that Mummy and Daddy take good care of the hamsters. With me at work and coming home late @ times, they give the hamsters the attention they need.

With 5 hamsters, there are 5 hamster "castles". There are 2 outside my room and another one near the dining room. At night, all the castles will be in the balcony and dining area.
