Why is my cat's poop black, and she stops eating after one bite?

This could definitely be because of the change of food but the black color concerns me that there may be digested blood present. Since she is so young and tiny, I would consider this urgent so I would try to get her into the vet soon. I would that she may become dehydrated or sicker if it isn't addressed. Your vet will likely want to run a fecal on her to check for any intestinal parasites. They may also want to know the food you are feeding her. I hope this helps and she starts to feel better soon.

Hello! If Bella hasn't been eating anything new, I am concerned that her black-colored feces could be a serious, potentially life-threatening situation. Black, tarry stools usually indicates bleeding in the upper gastrointestinal tract. Potentially, she could have a retained fetus, which could be causing internal damage. I highly recommend that you get her to the vet as soon as possible, for her life and the life of her kittens. Good luck, and I hope Bella feels better soon!

Black or tarry stool is a serious and concerning symptom that can sometimes indicate a bleed in the stomach or upper GI tract. Other issues such as parasites, food allergies, or ingestion of certain items may also cause the stool to darken or change colors. If Rowan continues to act oddly, has additional dark or tarry stool, or shows new symptoms of illness, seeking veterinary care in person ASAP is best.

Thank you for using Petco Pet Education Center, formerly Petcoach! Melena is essentially digested blood in the stool. This can be caused by bleeding in the stomach or intestines caused by ulcers, inflammation, clotting abnormalities, or a foreign body. I recommend having Billy seen by a vet as soon as possible to determine the cause of the bleeding. Your vet can perform bloodwork or an ultrasound to diagnose the cause.

Black stool can indicate that there is blood in the stool or something the pet ate disoclored the stool. If it only happened once and isn't consistently seen, then I wouldn't be too concerned about it. Just keep an eye on things moving forward, and if seen consistently then it's best to get Bella's stool tested by your vet. Best wishes and take care.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Precious! I think you should take Precious to the Vet today before the weekend. Three days is a long time to be sick and not be better. We don't like cats going more than 3 days with out eating. I would collect a stool sample to bring with you so the Vet can check for intestinal parasites. Causes of vomiting, diarrhea and not eating in an older cat are: kidney and liver failure, diabetes, overactive thyroid (hyperthyroidism), intestinal parasites, pancreatitis, inflammatory bowel disease and cancer. Your Vet, after their exam, will likely do blood work, check her stool for parasites and possibly take an X-ray of her belly. I hope this helps and I wish Precious a speedy recovery!

Black stool is concerning as that may indicate a bleed in the upper GI tract such as the stomach. If he is also vomiting and has had this ongoing for several days it would be best to seek out veterinary care in person ASAP.
