Blood in rabbit urine
Rabbit urine is often naturally red, orange, or brown from plant pigments and is usually harmless. True blood in the urine, however, can signal bladder stones or sludge, infection, or uterine disease (common in unspayed females) and needs veterinary assessment — urgently if your rabbit is straining, in pain, or not passing urine. If unsure, photograph the urine and call a rabbit-savvy vet.

What your vet may check

Recovery support after veterinary assessment
Once the cause is treated, your vet may advise hydration and daily support such as WOOLY Balance Water to support normal urinary habits.
Frequently asked questions
Is red rabbit urine always blood?
No. Rabbit urine is frequently red, orange, or brown from harmless plant pigments. True blood is different, and a vet can test the urine to be sure.
What causes blood in rabbit urine?
Bladder stones or sludge, urinary infection, and uterine disease in unspayed females are common causes. A vet exam and imaging help find which.
Why does spaying matter here?
Uterine disease, including cancer, is common in older unspayed female rabbits and can cause bloody discharge. Spaying greatly reduces this risk.
