It's a subject often debated at length between pet owners - whether or not to neuter a new pet.

Well, based on this cat's reaction to waking up finding he's had the snip, it could be suggested that cats and dogs favour vets leaving their private parts alone.

The hilarious photograph captures the moment six-month-old Milo wakes up from anaesthetic following an operation - only to discover he's lost a couple of things in his sleep.

Owner John Reed caught Milo's bemusement after getting him back home in Frizington, Cumbria, from a local vets.

John, 58, a property developer, said: 'It was priceless. He took about a good hour or so coming around.

'He looked down and realised they were missing and let out this almighty screech. He carried on looking down and staring for ages.

'I just chuckled. We've had a good laugh at the pictures since. The second one is amazing.'

John and his wife Julia, 59, had been planning on the operation at West Lakeland vets, Cumbria for a while.
