Can Birds Eat Raisins?
Raisins are unsafe for birds, causing renal toxicity and crop issues. The concentrated nephrotoxin can trigger fatal kidney failure, while the sticky, sugary texture promotes crop stasis and yeast overgrowth. Even small pieces can obstruct the crop or esophagus. The unknown toxin behaves similarly in avian species as in mammals, making raisins a forbidden food. Fresh, safe fruits like blueberries should replace any desire to share dried grapes.
