3-legged Cat

I go up Montjuic, a mountain in Barcelona which is a place of excursion for Barcelonians and tourists alike. There is a big parc, the Museum of Catalonian Art, two stadiums and – a lot of cats.

I have to think of a social system among street cats, where one cat helps the other. Makes me ponder about a cat help system or even a cat welfare state…
