Question: how long does it take for cat body to decompose?
Answer: In the spring, either coons, a fox or the returning turkey vultures would clear it up as soon as it thawed out and began to smell. If none of that happened, and it was a moderate summer period, I expect it would disappear within 10 — 14 days. Insects, maggots and grave digger beetles would clean it out and bury it.
