That’s a fantastic idea! I don’t know if those Asian cracker bunches count for firework approvals, but I’ve had them let off meters from the house without warning before --panicking both me and the cats.

If there is notice, I start playing some thumpy music (like Rammstein) very low several hours beforehand and up the volume every half hour or so. Seems to help somewhat. There is also a thing called a Thumdercoat.
