Urine colour

[oliviashutch]

Hi everyone,
I recently switched my hamster bedding from linum to white paper bedding and I noticed that some pees are darker than others. My hamster is a six months old female syrian, she is active and healthy, however I’m not sure if this is a regular urine colour.
Thanks!

That looks normal. The urine is quite concentrated in hamsters and can vary in colour depending on what they have eaten. Blood staining would not be normal obviously but that looks OK to me.
