Mindy's Hair Affair

This is my mama kitty and she hasn’t been in the house for 3 days. She rarely ever goes outside at all and is always here for her morning breakfast and lounging in her favorite chair in front of the window. I’ve had her about 16yrs. She would never stay gone this long and I’m wondering if something happened to her. She’s a pretty old lady. These are not the greatest pictures but she’s a petite kitty with an all white tummy and chest. Also all four of her feet are white. Her front left (?) leg was broken when she was a kitten so it’s kinda crooked and she walks with a bit of a limp. She is not chipped and has no collar as she rarely goes outside and definitely never leaves the front yard. She is fixed. Please let me know if you’ve seen her. We are in south Corvallis off of Ryan street near Bell street. If nothing else I’d like to recover her body and bury her at home. She’s the sweetest little cat and my heart is broken and I’d like to know what happened to her. Thank you.
