However, when he went to the veterinarians he was pleasantly surprised to find that the bill had been paid.
"It was the best thing someone could have done for me. There's still people who care in this town."
Meanwhile, Diego is glad to be home again and is getting around well. "He's happy to be home and happy to be back on my bed."
The incident is the second in recent weeks involving gin traps.
A cat's leg had to be amputated after being caught in an illegal gin trap in west Auckland last month.
The front left leg was nearly severed by the trap, which had been left on Silverstone Place in Henderson.
The cat was found by members of the public who placed him in a washing basket and contacted the SPCA.
The trap had bitten down to the bone and the leg had to be amputated.
The Government restricted the sale and use of gin traps in 2008.
