Indy's missing

I had planned to take Indy for his vaccination after I brought Pole and Cleo back, and I saw him under the neighbour's car when I left the house.  After I came home this morning, until now, I have not been able to find Indy at all.  I have walked up and down the road and looked into drains, he is no where to be found.

It's been many hours now.  Indy normally sleeps on top of the car in the porch. 

I'm really worried.

Indy, please come home.  I promise I will not take you to the vet's.
