Serving advice
Treat Watermelon 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 Watermelon and watch stools and appetite over the next 24 hours.
Safe seedless flesh in pieces. Remove all seeds and the rind (choking/blockage risk).
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
Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
