Can Rabbits Eat Rhubarb? No, rabbits should not eat rhubarb.
Rhubarb is toxic to rabbits and can cause serious health issues, including digestive upset, kidney failure, and even death if consumed in significant amounts.
Why Rhubarb is Unsafe for Rabbits
Rhubarb is dangerous for rabbits due to its high oxalic acid content, which can lead to the formation of harmful calcium oxalate crystals and severe kidney issues.
Both the leaves and stalks of the rhubarb plant contain toxins that can cause symptoms like lethargy, diarrhea, and abdominal pain, quickly escalating to life-threatening conditions.
Given its lack of nutritional benefits, rhubarb should be avoided entirely in a rabbit’s diet, which is best composed of hay, fresh vegetables, and safe, non-toxic fruits.

Symptoms of Rhubarb Poisoning in Rabbits
Symptoms of rhubarb poisoning in rabbits include gastrointestinal distress, such as diarrhea, loss of appetite, or bloating, which demand immediate veterinary attention.
Additionally, affected rabbits may exhibit lethargy and weakness, showing little interest in their usual activities—an indication that their health is seriously compromised.
The oxalic acid in rhubarb can also cause severe kidney issues, potentially leading to difficulty urinating or blood in the urine, with kidney failure being a life-threatening consequence.
