Australian charity Cat People of Melbourne has posted an unusual ad for a pet it's attempting to rehouse, describing the animal as an "utter b****** of a cat."

Mr Biggles, a short-haired domestic cat, is two years' old, and has "slinky shiny black fur and big yellow eyes."

However, warns the charity, Mr Biggles is an "utter utter utter b******" and is "not a cat for the inexperienced or faint-hearted."

The fearsome feline, who also goes by the name Lord Bigglesworth, is a "despot and dictator," the charity says. "He will let you know he is not happy, which is often because things are often just not up to his high standards."
