Udon was given a quarter of a carrot and I had simply left it on her cage's floor. After a while, I found the carrot in Udon's food bowl!
So I had decided to try again by putting the carrot far away from the bowl (at her sleeping area) and she tried moving the carrot to the correct place!
Udon really had lots of energy to lift this heavy (to her) carrot!
Please give Udon a round of applause for being a ORGANISED HAMSTER!
