Please spread the word for this lost cat by sharing this post.

💬 Owner's Message: "Cosmo went missing October 4 around 9 p.m. near Arthur St & Vanguard Ave. We’re very worried because he normally goes outside and always comes home within a few hours.

If you live nearby and have a moment, we’d really appreciate it if you could check garages, sheds, under decks/porches, bushes, or around vehicles, just in case he wandered in somewhere and became trapped by mishap.

Cosmo is friendly but may be shy with strangers. Please don’t chase him. If seen, please note the location and text or call Val at. An sighting helps. Thank you so much."

🐾 Description: "Brown tabby Scottish Fold male with a very round, owl-like face, small folded-down ears, and green-yellow eyes. Stocky/slightly chunky build with a thick tail and distinctive black rings. Friendly, but may be shy with strangers."

UPDATE: REUNITED!! Benny is home safe & sound after 1 days, 22 hours :)

🚨 Benny was LOST YESTERDAY in Thunder Bay, ON P7K 1E5 near Sandpiper Dr..
Please spread the word for this lost cat by sharing this post.

💬 Owner's Message: "🚨 LOST CAT — BENNY 🚨

Please keep an eye out for Benny!

🐾 Name: Benny
🐾 Location: Fairview Avenue, Thunder-Bay
🐾 Appearance: Long-haired black and white cat; tall and slender
🐾 Microchipped & neutered: Yes
🐾 Indoor cat: Benny has always been an indoor cat and has never been outside before.

Benny is very shy and timid, and because he has never been outside, he is likely very scared and hiding somewhere nearby. He will probably NOT come when called or approach people, so please don’t assume he isn’t nearby if you don’t see him right away.

Benny got outside after the back door was unexpectedly left/blown open for an extended period of time. We believe he may have gotten curious and slipped out.

❤️ If you see Benny, please do not chase him. If possible, take a photo, note exactly where you saw him, and contact us right away.

Please check around under decks, porches, sheds, garages, bushes, vehicles and other small hiding spaces. He may be tucked away somewhere very close by.

📅 Last seen: morning of September 13th
📞 Contact:"

🐾 Description: "Black and white, long hair, tall and slender, green eyes, male (neutered and microchipped)"
