Found: Grey tabby cat with red collar near Mercato Centrale

This afternoon around 2:45pm, I found a cat near the Mercato Centrale on Via dell'Ariento in Florence. It's a medium-sized grey tabby with white paws and a bright red collar with a little bell. I noticed a crescent-shaped white patch on the chest and a tiny notch in the left ear, and the cat was friendly and let me stroke it. It seems well cared for, and I think someone is missing this kitty; I'd love to help reunite them.
