Hi, my guinea pig just peed and it looks yellowy-white and its rather thicker than usual. He is eating and drinking fine. hes running around too, and not showing any signs of pain. What could this be? Does he need immediate care? (Please see the picture)

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!
