I have two 2-year-old indoor cats. One of them has been missing for 10 hours. I last saw her when I was leaving this morning - I highly doubt she got outside. I’ve been using tips on here to look for her and looked everywhere. I don’t hear any meows or movement.

Has this happened to anyone else? Did the cat ever come back? Why would she be gone for so long? I’m worried she’s injured or something.
