Hi Laura,
Here’s information of blood in stool:
Bright Red Blood in Cat Stool
Blood in cat stool that is fresh, bright red, and relatively liquid is called hematochezia. It is usually caused by bleeding in the colon or rectum. One occurrence of hematochezia may not be a problem, but if more than one episode occurs, you should take your pet to the doctor. Repeated events of this nature can be a sign of serious health issues including cancer in older animals or parasite infestation in younger pets.
Tarry Color Cat Blood in Stool
If you notice cat blood in stool that is black, tarry and more or less non-fluid, this can be sign of melena, which is what happens when the digestive fluid in your cat starts to work on the blood. The unusual color and consistency of this type of blood in cat stool can indicate old blood that has been digested much higher up in your cat’s intestinal tract.
Some of the other reasons for cat blood in stool include such things as bacterial infections, allergies, polyps in the colon or in the rectum, injury to the anal area or injury to the lower bowel, colitis and other inflammatory bowel problems, and parasite infections.
Symptoms of Cat Blood in Stool
In addition to seeing blood in feline stool, you may also notice some other symptoms or signs. These might include your cat straining hard when defecating or more bowel movements than usual. Your cat may also be more thirsty than usual or they may show signs of vomiting and diarrhea.
I”m not comfortable with any kitten/cat have blood in their stool. However, please review this info and if you’re still undecided then call another vet.
