Pulling up from work this morning I noticed a gray cat on walkway In front of my apartment . We have several strays so it is n't unusual to see on just lounging about . It was in front of my parking spot so when it did n't run as I was walking toward my apartment I was a little curious .
What may be the reason they were surprised when the stray cat did n't run ?
Pick the best answer from the following options:
- There was a mouse nearby .
 - They are used to the stray cats running away .
 - None of the above choices .
 - There was a bird nearby .


They are used to the stray cats running away .
