More Things in Heaven by John Brunner 

Not my cat

This is a local cat who has claimed a large territory in the neighborhood. Today he got it into his head to see if he could explore inside the houses he walks by. He did not get in but not for lack of trying.

(He lives in a nearby apartment building, I am told)

Very heavy, very muscular, likes attention, does not like to be picked up.
