Injured kitten peeing blood, vet found no internal bleeding. Why?

It could be a UTI, which would need antibiotics. Other possible causes include urinary bladder stones or congenital changes with the bladder or urethra. Since I am not sure exactly what is going on, I can't really tell you what to do. If you have access to antibiotics, you can try that, but we can't prescribe them online as it is illegal for us to do so.

This would not be uncommon as the bladder can become bruised due to the impact or pelvic damage. I would continue to monitor for any changes in frequency or discomfort when using the litter box which may require further investigation but in most cases this should resolve over 3-5days

This sounds quite frustrating for everyone involved! At this point, the most common causes of Greyson's bloody urine (UTI, kidney infection, crystals in the urine and bladder stones) have all been excluded. The other possibilities include a sterile cystitis (non-infectious bladder inflammation), urethral spasms or a bladder tumor (unlikely given his young age). Consider discussing medications that could decrease spasms in the urethra or anti-inflammatory medications to decrease bladder inflammation with your vet. Also make sure that Greyson is drinking plenty of water (water fountains or mixing water with canned foods can be helpful) because many causes of bloody urine can also be precursors to urethral obstructions, which can be life threatening. I hope that all goes well!

Poor guy. He likely has a urinary tract infection or cystitis (inflamed bladder usually due to stress). I would recommend taking him to your vet for a urine test to determine which is present so that he is treated appropriately. As long as he is otherwise acting normal and able to urinate at will, then it isn't considered an emergency at this point. Getting him seen on Monday or the day after should be ok. It is likely he will be prescribed antibiotics and/or a prescription diet to treat this successfully. I hope that Milo gets better soon. Best wishes and take care.

Poor cat! If the injury is serious as you say then kitty needs to be seen by your local vet for medical treatment and proper wound management. Depending on the nature of the injury, kitty may need sutures or staples, antibiotics and pain medication. Blood in the urine is a sign of stress, and weakness indicates that this kitty has a general illness such as infection going on that isn't being properly treated for. I seriously hope that your cat get the proper care soon and can recover from this unfortunate situation. Feel fee to request a consultation for more specific advice and to also share pictures of the wounds in question. Take care!

I would still recommend taking your kitten into the veterinarian to have an x-ray performed. She may have fractured the leg and just have a small hairline fracture without bone displacement. She would still need a splint or cast placed to help the bone heal. She may also benefit from some pain medication as well. As for the blood in her stool, I would recommend having a fecal examination performed by your veterinarian. It is very common for young kittens like this to have intestinal parasites that need to be treated with specific dewormers. There are other causes of blood in the stool as well such as dietary indiscretion, foreign bodies, viruses, or stress. Your kitten will likely need antibiotics and a dewormer to help the diarrhea clear up. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

I would be worried Leo hurt himself. I would take him into the emergency clinic right away to make sure he didn't injure something internally or suffer a concussion. Hopefully its nothing that serious but its best to be safe. I hope Leo is ok!
