My kitten has bloody diarrhea. Could it be Giardia from her sibling?

Poor kitties. It sounds like these kitties likely have an intestinal bug causing their symptoms. I would visit your vet to have their stools tested first to determine what bug is present, and then they can get prescribed the appropriate dewormer. They may also need to do a short course of antibiotics to get the gut flora back to normal, especially if you are seeing them straining (colitis). I hope that your little ones feel better soon! Best wishes and take care.

Since Nala is continuing to have diarrhea with blood, I would be concerned. I would recommend bringing her in to see your vet so a fecal analysis can be performed. Coccidia can often be seen on a fecal exam. There is always a possibility that this could be what is causing the problem, as well as other intestinal parasites. if she does have coccidia, she will need a different medication in the typical dewormer.

Yes, they can have Giardia or coccidia without any signs of disease and it can be missed by the lab depending on the test. There are a few different possibilities with what you are describing though. It could be a parasitic infection, but could also be a bacterial infection, or colitis due to an adverse food reaction. Considering you are seeing blood, it's best to have your vet recheck her. They will help to narrow-down the cause of this and provide the necessary treatment. I hope that helps and Kitty gets better soon.

It's possible there could be a parasite affecting both of them that started with the kitten, or something they got in to. I recommend they both be seen by your veterinarian. Bring a fecal sample with you to be checked for parasites.

Your kitten probably has colitis, which is an inflammation in the colon. This can be caused by stress, diet or changes in diet, and/or intestinal parasites. I would guess that Zia probably has all of these issues going on. It is not too early to take her to the vet. In fact, I would recommend it. Severe diarrhea can lead to dehydration which can be very serious in a little kitten. Your vet will need to check a fecal sample and may prescribe some antibiotics and probiotics and a dewormed for your kitten. I hope this helps. Best of luck.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Nami! At 6 weeks old Nami should be on 100% kitten food. She no longer needs formula. It could be her diet or the formula causing the diarrhea. Other causes of diarrhea in a kitten are: intestinal parasites and viral or bacterial infections. The blood indicates inflammation in the colon and the blood tends to show up with severe diarrhea or diarrhea occurring for several days. If Nami is eating and no longer vomiting I would eliminate the formula and the food you think upset her stomach. If the diarrhea isn't better in 2 days then bring a stool sample and have her seen by a Vet. If she won't eat or vomits again she needs to be seen. I wish Nami the best!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. Poor kitty! It's time to see the vet again since her poo is bad again with blood in it. She may have have something like coccidia or Giardia causing this issue, and those can take a while to treat. I'd take her back to the vet in the morning. Best of luck.
