Kale
Kale is nutrient-dense but contains isothiocyanates and calcium oxalates, which can cause gastric irritation and may affect thyroid function when fed in large quantities. Small, occasional servings are generally safe for healthy dogs.
Cats do not need kale in their diet and should receive only tiny amounts. Lightly cooking kale improves digestibility. Avoid feeding kale chips or seasoned kale dishes. Pets with hypothyroidism or kidney disease should skip kale unless approved by a veterinarian.
