They are all so cute! If the stool is firm and otherwise normal, the color could be a natural variation, but it can also indicate a bacterial infection. If the stool is loose (like diarrhea), then I would suspect there could be a bacterial infection. To be safe, I would take Angel and kittens into the vet now for a check up. Bring a stool sample for the vet to examine. Best of luck.

    The color I'm not worried about, but the less active part I am. Newborn kittens are very fragile, so I would have her seen by a vet immediately. Take her mother and siblings with her to the appointment. Best of luck.

    The poop could be due to a sudden change in diet, but it could also be due to intestinal worms, which are common in kittens. Make sure Tobi is up to date on his deworming treatments, and have him seen by a vet if these poops continue.

    Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely normal and just due to their current diet. Keep an eye on their feces and have your kitties evaluated by your veterinarian if you notive blood at any point as that would be concerning. However, their current stools are likely fine. Have a good day!

    This isn't normal and it can be a sign of overfeeding or a lack of production of bile. Even though they seem normal, you should still have them checked out by a vet to be safe. I'd take them into a vet this weekend for a health check. I hope this helps.

Is light brown or yellowish poop normal for my 6-week-old kitten?
In many cats, a light brown or yellowish color can be normal to the stool. If it becomes more of a pale yellow/white yellow, or becomes loose or has mucus or blood in the stool, these would be reasons for concern and a visit to the vet should take place.

Is yellow, fatty stool normal for a screaming newborn kitten?
This is fairly normal stool for a neonatal kitten, although it does look a bit watery. The stool should start to become more firm and brown as the kitten gets older. If it seems very watery or you are seeing blood or mucous there would be some concern. It might be a good idea to have this very young kitten examined by a vet regardless to make sure it seems to be healthy and to discuss proper bottle feeding and other care.

Vet Q & A
Why is my 3-week-old kitten's poop runny and yellow? Should I worry?
It is possible diva has parasites or the mother milk is giving it that look. I would start off by checking the feces for parasites including coccidia . This parasite can be treated with medications from your vet.

Vet Q & A
Why is my 3-month-old kitten's poop soft and yellowish? Is it normal?
It is possible Meshmesh could have intestinal worms causing his soft and yellow stool. Make sure he is up to date on his deworming treatments, giving him one if he isn't. He needs to be dewormed monthly until he is six months old, and then he should dewormed every three months thereafter.

Are my newborn kittens' black, hard, or hairy stools normal?
It looks like the one kitten may have a little diarrhea, which isn’t too concerning as long as the kittens are nursing well, gaining weight, and the stools form up a bit in a day or two. The black hard stool can be normal for the first stool passed, but I would keep a close eye on momma to make sure she is cleaning the kittens well. One of the best ways to make sure all kittens are thriving is to weigh them daily using a gram scale - they should gain every day.

My kitten's poop is now tan, firm, and smells. Should I worry?
Angel may have a bit of stomach upset or if you are feeding her something new like treats, that could be the cause of her poop changes. Keep an eye on her for now, and if it becomes diarrhea, have her seen by a vet.

Vet Q & A
I found a newborn kitten, what should its first poop look like?
Newborn poop can look like this and can normally be different colors and consistency. They eventually have more normal appearing stools after 2-4 weeks. For appropriate care of an orphaned kitten, I recommend you read the article at the following link: https://vcahospitals.com/know-your-pet/feeding-orphaned-kittens I hope that helps and all is well with the kitten.
