Please spread the word so we can reunite this found cat with its family! FOUND on June 9, 2026 in Thornton, CO 80229 near 88th and Grant/ Russel and Grant

Message from Finder: "They are very very sweet and look like they’ve eaten recently. Very welcoming and ran right up to us. We have given them some food and water as well in their time with us. I saw them a previous night and had to see if it was friendly since I’ve never seen a stray twice in the same area previously. They almost look like they have a dark eyeliner on the under eye and is giving you a disappointed face of concern. "

Description: Orange tabby with “dark eyeliner”

🚨Cyrus was LOST on June 6, 2026 in Northglenn, CO 80233 near 120th and Claude .
Please spread the word for this lost cat by sharing this post.

🐾 Description: "She’s dark grey. Her eyes sometimes look green but other times looks like the picture. She don’t really like people so she can seem offish and feisty…she’s super sweet just moreover protective of herself and her surroundings. She did lose a little bit of weight from being more outside. She usually stays close to home and comes back when I call her. But I haven’t seen her for almost 2 days. She was caught on camera (so we think) in the front yard around 12am-1am about 1 night ago. "
