Why it's dangerous
Soluble oxalate salts are absorbed from the gastrointestinal tract and bind with the body's calcium, causing a sudden drop in calcium levels and potential acute renal failure.
Toxic compound: Soluble calcium oxalate
Good to know
Soluble oxalates must be differentiated from insoluble oxalates, which are less toxic. While more common in livestock, large ingestions are dangerous for small animals.
