What few people know

It can outlive you: 50 to 100 years. Indoors it needs a UVB lamp every day, because glass blocks UVB.

What the law says

In the EU the three European tortoises (Testudo hermanni, graeca and marginata) are in Annex A of the wildlife trade rules: in Italy, buying or selling one, even as a swap, needs a certificate from the Carabinieri CITES units, plus a microchip and a declaration of possession.

How big it is

What it eats and how often

wild weeds, flowers and grass; little supermarket produce

  • Juveniles: every day
  • Adults: every 2 days

Mostly pesticide-free wild weeds and flowers: dandelion, clover, plantain, chickweed, sow thistle, white dead-nettle. Very little fruit; no peas or green beans (too much protein), no cabbage, broccoli or spinach; no lettuce. Calcium: cuttlebone grated over the food; vitamin and mineral powder on the food 2–3 times a week (the RSPCA says a light sprinkle every day). Clean water at all times, in a shallow dish.

Vaccines and checkups

None: reptiles don't need vaccines.

A checkup at the vet every year. With a reptile vet.
