If your pet has not returned after 24 hours, here are the actions to take.
Expand the search perimeter
Extend the search to 2 or 3 kilometers around the home. Stressed cats can cover significant distances.
Keep a journal
Note each testimony received, each clue. This helps cross-reference information.
Reward?
A modest reward can motivate searches but also attracts scams. Be vigilant.
Don't lose hope
Pets find their home after weeks, even months. Continue to broadcast notices.
