Orange pee? Normal or not?

[MildredMaudeandEnid]

I have a 14 week old piggy called Ethel and I noticed a spot of pee today that was quite orange. I had a search through some old threads on similar topics and found a mention that orange/rusty pee can be normal for young piggies. I've had her on a white pee pad for an hour to get a better look and her pees are definitely darker than her cagemates (which are clear and colourless). Can anyone advise if this looks normal? She doesn't have any other symptoms and doesn't seem to be in pain when she pees.

Top photo is initial pee that I noticed. Second is the pee pad. The dark one in the middle is Ethel's.

Guinea pig urine can oxidise when it reacts with the air turning it a rusty orange colour which is what you are seeing here. You’re also correct that young guinea pigs can have rusty orange wee. Nothing to worry about but please see your vet if you’re concerned

I have a phone appointment about my other piggy tomorrow so I'll mention it just to be sure. Thanks for the reassurance! I stress over them all the time!
