My young cat's poop is grey and discolored. Is it liver disease?

Pet's info: Cat | Mixed Breed | Female | spayed | 5 months and 25 days old

Hi i'm a little concerned regarding my 2 cats, ive noticed that for the last couple of weeks their poop has been discolourd and greyish. I've searched up online and the results are very concerning and state that they may have issues with their livers... They are both under a year old and are acting fine, as they are eating properly and playing together, aswell as taking naps often. i'm just very worried about them and i hope you could possibly help :)

I would be surprised if your cats both had liver disease and the only symptom was grey discolored stool. While technically liver and gallbladder disease can result in grey stool I’ve never seen it occur in practice. If you’re concerned or if your kitties begin vomiting, have a decrease in appetite, or develop diarrhea you could see your vet to have them check blood work.
