Cream-and-brown guinea pig with white blaze

I lost my cream-and-brown guinea pig, Ziggy, yesterday around 3pm. He has a white blaze on his nose, soft fur, and wears a tiny blue collar with a small silver bell that jingles when he moves. Last seen near the Tesco Express on Romsey High Street, Hampshire, just past the library by Market Square. Ziggy is more than a pet—he was a gift from my sister, and I’m really worried about him. If you've seen him, email [email protected] with any details.
