Are my newborn kittens' black, hard, or hairy stools normal?

Updated On September 23rd, 2025

Pet's info: Cat | Persian | Female | unspayed

Hi, so my cat, Fifi, gave birth to three kittens yesterday. The kittens are doing fine today, though I noticed their stool was black, hard and stuck. I cleaned them with a warm cotton ball. I also noticed a while ago that the kitten’s stool was very golden in colour and had long hair? in it. The smell it was omitting was also very strong; smelled like pargo in newborn puppies. I was wondering if this was all normal or I need to be concerned. Thanks!

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.
