Appearance: Healthy cat excrement is usually brown, cake-like or sausage-like, with a certain softness. If the stool is abnormal in color or shape, there may be some digestive or intestinal problems.
Smell: Healthy cat excrement usually has a certain smell, but it is not too pungent or smelly. If the smell of poop is unusually strong, there may be intestinal infection or other diseases.
Quantity: Under normal circumstances, cats defecate 1-2 times a day. If the amount of stool increases or decreases abnormally, it may be intestinal problems or other diseases.
Digested food: Sometimes undigested food can be found in feces. If it happens frequently, indigestion or other problems may occur.
It should be noted that these indicators are only preliminary judgments. If you find that the cat has an abnormal stool, you'd better take it to the vet for examination to ensure its health.
