My rabbit peed blood. Is it an emergency? When should I see a vet?

These signs might be compatible with a urinary tract infection/inflammation. These signs must be checked as soon as possible as urinary tract infection can be dangerous in rabbits as can lead to stress and degenerate to more systemic signs. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed.

I would look them over carefully for any signs of injury and bleeding in case they were fighting. If you can't find anything significant, make sure that neither one is urinating blood as bladder stones are common in rabbits and this is the most common sign of this problem. If you find any wounds that seem deep, or if you think someone is peeing blood, he or she needs to see vet at your earilest convenience. Hopefully it was just a fluke!

The first thing I would want to find is if the urine really has blood in it. Rabbit's urine can often look like it has blood in it, because they excrete a certain pigment (porphyrins) in the urine. This can be due to a diet high in carotenoids (carrots, mango, papaya, other orange fruits and vegetables) and stress. Blood in urine can also be a sign of infection. The best thing you can do is get the urine tested by a veterinarian. If Thunder otherwise seems fine, then it would be OK to wait a day or two and see if the urine does not look like it has blood anymore. Keep in mind that a rabbit's diet should be mostly grass and hay. Fruits and vegetables should be less than 10% of their diet. Also make sure that Thunder has a bowl of clean water available at all times.

It is possible your bunny has a urinary tract infection (red urine and urinary accidents can both be seen with this condition). Another possibility would be a bladder stone or tumor. Your bunny should see a veterinarian to check her urine, and start an antibiotic if needed or have an x-ray if no sign of infection is seen in the urine.

Your rabbit has likely got a case of cystitis which is bladder inflammation. If you go to tge vet they can give you antibiotics and antinflammatories to treat it. If it has been going on a while there is a chance that infection has gone up to the kidneys which is more serious.

This looks like blood in the urine with possible blood clots, you will need to take Plush to the vet ASAP in order to get it checked, if he is suffering from a urinary infection he will need to have a course of antibiotics.

It isn't normal at all and is probably a sign of a severe gastrointestinal infection, unless you are mistaking and it's actually coming from the urinary tract, in that case it could be a urinary infection. either way it needs to be treated urgently, you need to take her to the vet ASAP in order to get it treated.
