A Destruction of Cats!
However, there is one place where our feline friends continue to thrive.
A large, leafy and very secluded courtyard is home to a sizeable colony of feral cats. The courtyard is very well hidden behind the church of Santi Giovanni e Paolo (aka San Zanipolo) and can only be accessed via the hospital. It is a peaceful place, well-furnished with benches, and I often used to go there to read. The cats might be feral, but most look remarkably sleek and well-fed.
I have just discovered that the collective noun for a group of cats is a clowder (or clutter, cluster, glaring and pounce). And if the cats are feral, it is a destruction. The things one learns on the internet!
