Town in Italy starts using Silent Fireworks as a way of Respecting their Animals (link)
Any large celebration that involves fireworks is fun, but while we enjoy the sounds and sights of colourful explosions overhead, our animals feel very differently.
The explosions caused by fireworks have been known to give some domestic pets heart problems, nausea, tremors, debilitating fears and light-headedness. We all know that animals have far more sensitive hearing so you won't be surprised to read that firework displays can leave pets with “acoustic stress”.
During firework displays animals are often confused as to where the loud noises are coming from which makes them run frantically away. Unfortunately, this sometimes results in them being hit by a car. Other animals may be too close to the explosion and receive burns or eye damage as a result. If you keep chickens, you might find that they produce fewer eggs after a firework display.
This would be helpful for veterans with PTSD as well.
