Reddish urine
My guinea who is a 5 year old female with a very large inoperable tumor had a strangely colored pee this morning. She didn’t cry or seem to be in pain when it happened. I also haven’t given red veggies or food out of the ordinary except for recent pear sticks which she ate quite a few of.
How emergent would this be and is a vet visit required? I hope to not take her to the vet unless ABSOLUTELY necessary. Due to her respiratory issues from the tumor, last time I took her to the vet the stress caused her to hyperventilate and turn blue and she had to be put on oxygen. It was very traumatic. The vet is closed though until Monday so I won’t be able to hear back from them until then.
EDIT: I just watched her pee again and it came out yellow and then after approx 10 seconds it turned red. I feel like it’s not blood now, but I’ve never seen this happen before.
