Something is making nests in our cars

[u/AelinGalathynius01]

Some kind of animal (assuming a rodent) is making our garage, and our cars, its home. It keeps dragging cracked corn, bird seed, moss, pheasant feathers (dad is a hunter), and random garbage items into our vehicles. We thought it was a mouse but found some scat today and it’s clearly not mouse poop. Any ideas what this could be?

We live in the northeast US.

Squirrel poo should be a bit bigger.
