Record Keeping
Keep records of your tortoise's weight, length, and of any illnesses or
veterinary treatment it may have had. These records will help you to know whether or not
your husbandry is successful. Weekly weights are sufficient if the tortoise
is healthy and active, but weigh more often if problems occur. Many problems
can be diagnosed and treated more successfully by reference to records. The
correct (weight)/(length cubed) ratio for adult Testudo graeca or Testudo
hermanni is .21 to .23 g/cm3. Hatchlings should have a higher ratio. The
length used in this calculation is the straight line length between the
supracaudal and nuchal scutes.
Healthy tortoises should not be too light or too heavy, but should grow in proportion,
indefinitely. There is no such thing as a 'fully-grown' tortoise. For three
weeks, before hibernation, the tortoise should lose weight. Over hibernation
its weight should remain virtually constant. For three weeks after
hibernation it should replace the weight lost in the autumn, then steadily
gain weight over the summer. On any date, the tortoise should weigh more than
it did on the same date last year. It is impossible to check this unless
records are kept.
