Rhubarb leaves are strictly unsafe for tortoises. They contain extremely high concentrations of soluble oxalates, which can cause severe oral irritation, acute kidney failure, and dangerous drops in blood calcium. Even small nibbles can trigger serious poisoning, so you should never offer rhubarb leaves or grow them where your tortoise roams.

๐Ÿšจ Emergency: Yes โ€” contact your veterinarian immediately.

๐Ÿ’ก Why

Rhubarb foliage contains dangerous levels of oxalic acid and soluble oxalate salts, along with toxic anthraquinone glycosides. When ingested, these oxalates bind readily to circulating calcium in the tortoise's bloodstream, forming insoluble calcium oxalate crystals. These sharp crystals lodge directly in the renal tubules, which can cause rapid, life-threatening kidney damage and severe metabolic disruptions.

๐Ÿฉบ What to do

  1. Remove any remaining rhubarb leaf from your tortoise's mouth and habitat immediately.
  2. Place your tortoise in a shallow, warm water soak to promote hydration and support kidney function.
  3. Contact an exotic or reptile veterinarian immediately for guidance, providing an estimate of how much plant was consumed.
Important: this is for reference only and is not veterinary advice. If your tortoise may have eaten or touched something dangerous, contact your veterinarian immediately.

โ“ Common questions

Are cooked or dried rhubarb leaves safe for tortoises?

No, cooking or drying does not destroy the oxalic acid content. The foliage remains highly toxic to reptiles in any form.

Can tortoises safely eat the red rhubarb stalks instead?

No, while stalks have lower oxalate levels than leaves, they are still far too acidic and high in oxalates to be safe for your tortoise.

What symptoms indicate my tortoise ate rhubarb leaves?

Watch for lethargy, drooling, foaming at the mouth, loose droppings, and a sudden lack of appetite or changes in urate production.
