Putting the cat box outside will help guide them home. They smell their scent for blocks. If indoor only, they will stay close to home unless chased. They hide anywhere they can, so look in places you wouldn’t think a cat could get into. Check with neighbors and put up signs.
You and your pet belong together. Your cat or dog’s microchip implant gives your pet the best chance of returning home to you if lost. However, a microchip must be registered along with your current contact information in order to identify you as your pet’s parent. Remember, as long as there are pets, even those belonging to the most responsible parents will go missing.
