Mrs Petrillo, 35, a manager for a wine company, returned to the couple's old home a mile away - and immediately recognised the cat as Alfie.
The three-year-old had lost the collar he used to wear and had put on weight, suggesting someone else had been looking after him while he was being mistakenly mourned.
Mr Petrillo said: 'It was just unbelievable - the cat I had buried nine months earlier, the cat we spent about a month grieving over, was back, and my wife just couldn't believe what she was seeing.'
The Petrillos still don't know whose cat they buried, or where Alfie has been all that time. Link -via Digg
