My tortoise has undigested food in its faeces what could this mean?
This could be flagellate organisms/parasitic invasion. Symptoms include diarrhoea, passage of undigested food, dehydration and anorexia. Although your tortoise may still be eating, the undigested food is in effect starving the tortoise. The tortoise should have a reptile vet’s attention as soon as possible. A fresh faeces sample should also be taken to confirm the presence of parasites.
