An unlikely friendship between a cat and dog has began an online frenzy with more than 500,000 YouTube hits.
Matt Hirst, of Woodseats, Sheffield, caught his pets on camera working together to open the kitchen door while he was out.
The 31-year-old IT technician has been overwhelmed by the response to the video.

He said: “It has been crazy, my initial surprise was when some viewers commented saying the video was fake, but it definitely is not.”
The video captures one-year-old tabby Dexter working with Gizmo to escape from the kitchen while their master is away.
The little Yorkshire terrier watches Gizmo climb to the top of his toy and paw at the handle, opening the door for the pup to walk through.
Shortly after best friend Gizmo follows her out of the kitchen. The end of the video sees cheeky Dexter pop her face around the corner for a final few seconds of fame.
At first Matt thought someone had been breaking in.
Convinced he was leaving the house before work with all the doors closed – but not sure whether Dexter and Gizmo were the culprits – he set up a home video to run while he was out of the house.
Matt said: “The first time I assumed I just left the door open. The second time, I checked the whole house thinking that someone was breaking in but it was then I begun to suspect the cat.
“The third time I figured it must be the cat and decided to catch him out, so set the camera up and left it going all day.”
Matt initially put the video online so interested friends and family could see it. But just one week later Dexter and Gizmo have become stars with more than half-a-million YouTube hits.
Matt looks after the cheeky feline-canine pair with his partner, Kate Copley.
Kate, 24, cared for Gizmo before she met Matt, but there was no need to worry about their pets not getting along.
Matt said Dexter and Gizmo have always been the best of friends.
He said: “The cat used to suckle and groom the dog when he was a kitten, presumably thinking she was his mum. The video success has been a joint effort – it wouldn’t have been as popular without Gizmo.”
The pets have sparked interest all over the world, with Matt receiving calls from TV companies in Japan.
He said: “It has been remarkable, I don’t think they know any other tricks but you never know.”
