Serving advice
Treat Mussels 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 Mussels and watch stools and appetite over the next 24 hours.
Cooked and removed from the shell, in small amounts. Raw shellfish carries bacteria.
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.
