Missing cat

[Edit] Found her today! She was about four houses down the street, missing her collar but she’s home now! Happy holidays everyone! In the vicinity of Crosby Crossing, SE 8th St, Midwest City My partner and I recently took in a stray cat (that we named Momo) as we were moving out from Norman and this past week I had just taken her to the vet to check if she was microchipped. She wasn’t and I set up an appointment to get her spayed at the earliest opening which is understandably after the holidays. Last night my partner and I were hosting a few friends and we think she slipped out when one of them had to step outside. She’d been yowling all day and had enlarged nipples so we’re pretty sure she’s in heat. We think she slipped out around 11 last night and we haven’t seen her since. We haven’t let her go outside since there’s at least one stray dog that wanders the neighborhood and I’m worried it might scare her away or confuse her. I’ve talked to a few neighbors but no luck as of yet and there’s a lot of houses around. If anyone has seen this tuxedo cat (last seen wearing a green collar) please DM me.
