Sure thing. Build a solid perimeter, add a few well‑placed pitfalls, and keep the entry a single gate you can lock. Make the traps low‑maintenance so you don’t have to keep patching them up. For the joke—paint a “Beware of Ninja Cats” sign over the trap door. It’s a distraction, it’s a laugh, and if the cats show up you’re already prepared. Stick to the plan, don’t over‑complicate, and you’ll have a bunker that lasts and keeps the spirits up.
