[dustybaby]

Shown below is my russian dwarf hamster’s (named dusty) urine in his wheel (for some reason he uses his wheel as a toilet). I need to know if this colour is normal or if he is ill.
Some information that could relate or help with this: dusty drinks the normal amount for a hamster (about 2/3 times a day), in the food/muesli that I feed him there are some red biscuit things as well as what I think is flakes of corn that could cause this colouration, there are some things in his cage (hides, chews etc) that could cause this colour but i am not sure, there is no stains or any other trace of this urine in his bedding which is white so we would easily be able to tell if there was, and dusty does seem healthy and happy.
Please help me know if this is normal and i will give more information if needed.
Thankyou.
