The food caching of grey squirrels can get a little absurd in neighborhoods like the time someone discovered hundreds of walnuts had been tucked away in the engine bay of their car ( source).Ī Squirrel’s Body Heat Is Essential To Survival Grey squirrels will create multiple food caches in case one of them becomes compromised. American red squirrels will build up a single massive central food cache called a midden and will spend the winter fiercely defending its single food supply.
