Lost Pet: Pippin

Circumstances

Pippin hasn?t been seen since yesterday (Tuesday, 24-Sep) and we think he may have got out somehow without us noticing, maybe when one of us was taking out the trash. 
He has been living at my dad?s in the Palo Alto/Barron Park area on Paradise Way with our other indoor cats since January while our house is being remodeled. I?m worried he won?t know how to get back to my dad?s house or find his old home with us being remodeled a few blocks away (Timlott Lane). My dad has posted on Nextdoor and we have been wandering the neighborhood calling for him. He is very friendly,  doesn?t seem to get scared easily and loves to be petted. Please let us know if you have seen him. He has a microchip. His name is Pippin but we also call him Fluffy.
