Blood!?

[gp-d]

I just went to see my guinea pigs earlier and there was a spot of urine but it looked sort of red rather than the usual, so blood basically I'm guessing. I'm not sure which pig it belongs to but can anyone tell me what may be causing this?

Sometimes mine have done a rusty coloured piddle - normally its clear, but apparently a brownish one is normal too..

Have you fed beetroot? this can cause reddish wee & i think dandelion leaves can too :-\
