Re: Strong coloured piddle

If there are no signs of blood I would worry too much:

"NORMAL:
Urine may be clear to cloudy in color. Calcium compounds in the urine
cause this cloudiness. Normal urine is not gritty in texture. Dried
urine may leave powdery white calcium compounds. Very young guinea
pigs often have an orange or brown tint to their urine. Urine
sometimes changes to an orange color on standing (this may be the
oxidation of ****phyrins in the urine)." -

Was the urine orange as it came out? Or did you see it after it had
been there for a while? Is there any noise or discomfort when they
urinate? And are they eating/drinking as normal?

It sounds fine to me going from the above info, keep an eye on them
and if you're worried, take them to a vet just to get them checked for
a urine infection etc...

Hope this helps!
