Cats with concrete pillows

Clearly, this is a couple of street cats but curiously they are using concrete parking stops as pillows.

The lumps of concrete are designed to stop a driver driving into the low wall at the edge of the parking lot. The tyres contact these blocks to remind the driver that they are at the limit of the parking area. They remind me of my cat actually. My cat likes to rest his head in this position on my leg. It's an alternative to the curled-up position. However, it does not look that comfortable. I have a feeling that they are siblings. 

Probably like you, when I see this photograph, I want to help them. They should not be living like this. It is an interesting photograph but also a sad one.
