Safety Overview
Spinach is generally safe for healthy cats when fed in moderation and cooked. However, spinach contains oxalates, compounds that can contribute to the formation of calcium oxalate crystals and stones in susceptible cats. Cats with a history of urinary tract issues or kidney disease should avoid spinach entirely. For healthy cats, small amounts of cooked spinach as an occasional treat are unlikely to cause problems.
