Serving advice
Treat Spinach as a snack rather than part of the daily ration — the usual ceiling is about 10% of daily calories. Start with one small piece of Spinach and watch stools and appetite over the next 24 hours.
Small amounts are fine; large amounts of oxalates can be hard on the kidneys over time.
Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.
There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter
A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.
