| Texture of feces | Color of feces | Presence of blood | Occasional accompanying symptoms | Most probable cause |
| Stringy, semi-solid / loose / diarrhea | Light brown / green | Usually none, but can be present in cases of heavy infestation; usually seen as bleeding from the mouth | Appetite loss; weight loss, sometimes sudden in onset | Nematode infestation: Crenosoma striatum |
| Semi-solid / crumbly:- undigested food present | Light brown | Usually none | Mediocre appetite; very little/no weight gain or gradual weight loss | Nematode infestation: Capillaria erinacei or trematodes such as Brachylaemus spp. |
| Mostly normal, but sometimes slightly loose | Normal color (dependent on food eaten) with dark green segment at one end of stool | Usually none | Weight gain might be a little slower than expected | Hymenolepis erinacei |
| Diarrhea | Bright/very light green | Usually present. Amount signifies degree of progression of the infestation/damage to gut wall | Appetite loss | Protozoan infestation: Isospora, resulting in Coccidiosis |
| Diarrhea | Brown | Large amount of blood produced from mouth and anus due to hemorrhaging tissue | Extremely rapid weight loss leading to emaciated appearance, dehydration, collapse then death if not treated immediately | Bacterial infection: Clostridium perfringens or threadworms such as Capillaria aerophila |
| Diarrhea, very watery | Brown | Not usually | Extremely restless. Often seen walking purposefully in the daylight, usually followed by collapse due to exhaustion and dehydration | Bacterial infection: Escherichia coli |
| Semi-solid / loose / diarrhea | Dark green | Occasionally | Appetite loss | Bacterial infection: Salmonella spp. |
| Dry, hard stools | Black / brown (color essentially determined by diet, but darker than normal) | None | Appetite loss and occasionally restless | Recent treatment for intestinal worms, which may have resulted in a blockage / food too dry |
