It's sad for the area. There is a lot of bad blood here from the civil war. This was an anti Franco region. There are families here split because of this political divide. The land that these houses are built on was sold by a family that supported Franco in the civil war. In the war one of the sons of this family was shot by the pro Catalan movement. Ask around and the locals say they developed the land like this out of spite.Sounds like a sad situation for all the animals involved Shad...sad for the ones left to their own devices and sad for those that bear the burden of coping with unmanaged "pets".
There is a lot of history here right back to the Romans.
