Calico guinea pig with blue harness

Hi, I’m Amina. I lost my calico guinea pig yesterday around 3:15pm. Her name is Nibbles. She escaped from her cage while we were at the Watertown Public Library on Main Street, near the reference desk. She’s small, about a pound and a half, with calico fur in orange, black, and white, plus a white bib on her chest and a tiny black spot on her left ear. She wears a blue fleece harness with a tiny silver bell. She’s very friendly but shy, and my daughter is crushed—we really need her back. If you spotted a little guinea pig around that area, please drop a note here and we’ll arrange pickup.

Black leather Samsonite briefcase with red lining

I lost my black leather Samsonite briefcase yesterday around 3pm near the Watertown Public Library on Main Street. It’s a medium-sized case, about 15 inches wide and 11 inches tall, with a small dent on the top-right corner and a chrome name plate that reads 'A. Kapoor'. Inside are a stack of work contracts, a small notebook, and a dog-eared family photo tucked under the flap; the red fabric lining makes it stand out in a hurry. It has sentimental value for me because it also contains a note from my late grandfather, and I really need it back for an urgent client meeting tomorrow. If you’ve seen it, please message me here so we can arrange a pickup—I’d be incredibly grateful.

Blue North Face backpack with hedgehog sticker

I lost my blue North Face backpack yesterday around 3pm near the Watertown Public Library on Oak Street. It's a medium-sized backpack with faded blue fabric, black trim, and a slightly squeaky zipper. There's a small hedgehog sticker on the inner pocket and a dent on the lower left corner. Inside I kept a gray laptop sleeve, a charger, and a photo of my grandmother—this bag has sentimental value to me, and I really need it back. If anyone found it, I’d be grateful to arrange a meetup downtown to return it.

14k gold ring with emerald and initials

I lost my 14k gold ring with a tiny emerald set in a delicate bezel yesterday around 7pm near the Watertown Town Center, outside the Watertown Books & Café on Main Street. The ring is about a half inch wide, with a subtle milgrain edge, and there's a small engraving inside that reads 'M + L'. It was a gift from my grandmother and means a lot to me, so I’m really hoping it turns up. If anyone found it, I’d be incredibly grateful to get it back—send me a message here on the app and we can arrange a safe meetup near the fountain by the town center.

Black-and-white dog with blue collar

I lost my 4-year-old border collie mix, Nova, yesterday around 6pm near Watertown Square, at the corner of Main Street and Orchard Street. She's medium-sized, about 40 pounds, black with a white chest and a heart-shaped patch on her chest. She wears a blue reflective collar with a small brass bell, and there’s a tiny scar above her right eye from a past scrape. She’s super friendly but gets spooked by loud noises, so she might bolt if you call out. If you’ve seen her, please text me right away—she's part of our family and we’re really worried to have her home.

Gray Anker Bluetooth speaker found near Watertown Library

I found a gray Anker Soundcore Bluetooth speaker this evening around 7pm in the parking lot behind the Watertown Free Public Library on Main Street. It's about the size of a paperback, with a blue silicone bumper and a small dent on the bottom corner. The top panel shows a little wear, and there’s a panda sticker on the back that says 'Relax'—easy to spot in a crowd. I tested it quickly with my phone and it connected normally, so it seems functional. If this is yours, please reach out—I know how frustrating it is to misplace something that gets a lot of use.

Tan Michael Kors tote found near Watertown Public Library steps

Found a tan Michael Kors tote this morning around 9am near the Watertown Public Library steps on Main Street. It's pebble leather with a small gold MK plaque on the front and a long crossbody strap that is a bit scratched from city wear. The interior is black fabric with a zip pocket that holds a pink enamel heart charm on the zipper and a receipt from Luna Boutique dated last Friday. I didn’t recognize any student IDs or cards in there, so I figured the owner would appreciate knowing it turned up. Happy to arrange pickup near the library for whoever lost it.

Found portable projector with case

I found this portable projector this afternoon around 2:15pm in the parking lot behind the Watertown Public Library on Oak Street. It's a compact black cylinder, about the size of a soda can, with a matte finish and a slightly scuffed top rim from travel. It came with a short HDMI cable and a gray carrying bag, and there's a blue sticker on the bottom that reads 'STEM Club - Property' which I thought looked like a school item. If this belongs to someone, I can arrange a quick drop-off at the library front desk.

Black leather briefcase with red interior

I found a black leather Samsonite briefcase this afternoon around 4:15 pm outside the Watertown Courthouse on Main Street, near the Oak Street crosswalk. It’s a medium-sized case with a gold-tone combo lock and a red interior lining that’s a bit worn. Inside, there’s a blue spiral notebook with a sticker that says 'Q3', a USB drive, and a business card for Elena Park tucked in the front slip pocket. There’s a small coffee stain on the bottom corner and a light scratch along the edge. It seems someone was on their way to a meeting; I’d love to get it back to Elena Park or the owner. If you recognize these details, please message me.

Blue compact umbrella with teal handle

I found a blue compact umbrella this afternoon around 3:15pm near the Watertown Public Library on Main Street. It's about 10 inches long when closed, with a bright teal handle and a tiny enamel cat charm hanging from the strap. The fabric has a few minor scuffs but the spokes look intact. It was leaning against the bike rack by the library entrance, waiting to be picked up. If it's yours, tell me the charm color and approximate shade of the blue fabric to confirm ownership.
