Spinach

Is spinach poisonous to cats? I looked at several websites and found conflicting information.

- Lauryl B.

Good question, Lauryl. There is currently no solid data pertaining to feline ingestions of spinach, but we do know that it contains a small amount of calcium oxalates. While a leaf or two may not be an issue for a healthy adult cat, chronic and/or large ingestions of spinach could potentially cause crystal formation in the urinary tract. (And P.S., Because of this, spinach should be avoided completely in any cat with a history of urinary problems, including infections, crystaluria and kidney disease.)
