I am surprised to read Suzie Wainman is angry about her cat Saffie having been returned to her neutered and microchipped (February 21).

In all probability, these interventions will prevent Saffie from being lost in the future. Un-neutered cats will travel miles looking for a mate. These are often the ones that become stray and rely on rescue shelters to care for them.

Microchipping is surely a sensible option if your cat wanders. Perhaps, when emotions have settled, Saffie's owners may appreciate the cat shelter's actions have prevented her from the risks of being lost in the future.

On a general note, rescue centres have thousands of abandoned and unwanted cats in their care. One un-neutered cat can be responsible for 20,000 descendants in five years.

All cat owners should think carefully before adding to the problem.
