Guinea pig urine, like rabbit and horse urine, is full of solutes and so can look really cloudy and be totally normal. This does not look concerning to me. The color and consistency of urine and feces in these creatures changes based on what they eat, so new treats or food can change how the urine looks. I would not worry at all. Hope that helps!

Thank you for your question. Guinea pigs can certainly develop urinary stones. The white gritty substance you describe sounds like ge may be developing grit or urinary sand type stones. He may also have a large stone in his bladder. I would encourage you to have him evaluated by your veterinarian soon. An x-ray and urinalysis may be recommended. Best of luck and thank you for using Pet Coach.

Pigs can have urine that varies in color, and this looks normal to me. Pigs are, however, prone to getting bladder stones, and usually when this happens the urine starts to appear bloody or red-tinged. Your pig is awfully young to be having bladder stone issues, but the only way to know for sure, and if you are worried, is to have a bladder ultrasound or radiograph taken to look for stones, and to examine the urine for any signs of infection. If you are still worried, I recommend doing this for your peace of mind. Hope that helps!

My guinea pig has cloudy urine. Is this normal or a concern?

This can be normal. Calcium compounds in the urine cause this cloudiness. Without seeing them in person, however, I can't say for certain it's normal, so I would have them checked out by a vet to be safe. Best of luck.

My guinea pig's pee is white and milky. Should I be concerned?

Hello. A milky white urine could be an indication of pyuria, or infection in the urinary tract. Too much phosphorous in the diet or crystals in the urine can also cause the milky white color. Please make sure Coco's diet is primarily timothy based pellets & hay. Make sure you are not feeding too much in the way of spinach, parsley or celery. Also, make sure you are not overdoing the Vit. C & D supplements. You might want to have the urine analyzed just to make sure this is not anything else that may require additional treatments.

Why is my guinea pig drinking a lot and has thick, cloudy pee?

Your skinny pig is very cute, I love thes guys! The increased drinking can be a number of things from a urinary tract infection to a teeth problem! Guinea pigs can pass creamy urine from excess calcium in their urine from diet or from a uterine issue. She will need to see a vet and have them check and see what is going on. If you can get her to go pee on a flat, clean surface, you can take it in to your vet. It should be in the fridge until you take it in. Make sure she is is getting low calcium veggies (like Romaine, Endive, Escarole, Cilantro and bell peppers), no alfalfa hay and Adult GP pellets that are free of Alfalfa.

My guinea pig has dark orange pee. Is it serious? What should I do?

Guinea pig pee comes out clear, but can oxidize and turn orange when it's exposed to the air. You might not have anything to worry about, just try to catch her on the act, if it is clear she is likely fine.

My young guinea pig has dark brownish urine stains. Should I worry?

Thanks for reaching out about Beto. Dark urine can be the result of carotenoids in the urine (from yellow/orange veggies) or other pigments. Although blood is possible, not common in young guinea pigs, but possible. Removing these vegetables from the diet for a short period of time, might change the appearance of urine. Good luck.

My guinea pig has creamy pee and big belly. Is it a bladder infection?

Some guinea pigs can have problems with a urinary infection and/or bladder stones that can cause their urine to look like as you described. This is not normal. If Peaches is pregnant this could be a serious problem. It's a good idea to have your vet examine Peaches and do a urinalysis to check for infection and other problems. Hope this helps. Best wishes.

Why is my guinea pig's urine pink? Is it blood? Should I worry?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Lucy. Poor girl! This looks like she has blood in her urine and this can be caused by a UTI, or urinary stones in the bladder or kidneys. She needs to see a vet for this problem to get it diagnosed and treated. I'd take her into a vet today. I hope this helps!
