One Street Cat

street cat
slumbers
on a sandstone step
the comfort
of a well placed mat

One Street 15

Given my One Street is about four miles long, recording each cat that I meet along the way might be a project in itself.  This one has squatters rights over number 272.

Unrelated, but it struck me that my three entries before this one have something in common which may not be immediately discernable. Can anyone spot the common feature?
