A cat owner with a very mischievous feline has revealed he has been stealing from the neighbours during his night-time jaunts. 

Rachel Ward, 34, from Anglesey, Wales, recently discovered that her one-year-old black cat, Marvin, has a penchant for theft. 

To her horror and bemusement, Marvin has been scaling a neighbour's property and returning home with an assortment of stolen goods.

What began as a baffling discovery of miscellaneous objects in her living room has now become a regular occurrence, with Marvin frequently returning home with his latest haul. 

Marvin began his elusive heists on June 4, starting modestly by bringing two socks back to Rachel's home - but since then, his collection of acquired items has grown considerably.

His choice of items seems random, with no particular preference evident in his loot. 

The feline's escapades have become so frequent that Rachel often arrives home from work to find new additions to Marvin's stash. 

Marvin takes pride in his finds, with one telling image showing him sitting territorially on top of his heap of stolen goods, perhaps guarding them from being returned to their rightful owner.  

Reflecting on her cat's peculiar behaviour, Rachel said: 'When I get home from work, there would be new items on the floor.'

She added: 'Sometimes he comes in and makes a noise to say that he pleased with himself and looking for gratification.'

Marvin's thieving antics means he joins a host of felines across the globe that are classed as being kleptomaniacs. 

Kleptomania is mental health condition in which a person experiences a consistent impulse to steal items they do not need, according to Psychology Today

Experts from Catster suggest that some cats exhibit this kind of behaviour if they are bored, stressed, or as a form of hunting, driven by their natural instincts to capture and present their 'prey' to their owners. 

In Marvin's case, his 'prey' just happens to be a variety of household items from the neighbourhood. 

It comes after furious locals demanded a red-faced church minister keep her kleptomaniac cats inside - after burgling sprees saw them swipe a little girl's ballet shoes, a dress and even a pet hamster.

Julie King, from Redmond, Oregon, first realized her cats Catty and Cali were shameless thieves two years ago when she collect their haul in a sack before dumping it on her neighbor's doorstep to return it.

But when two pink dance slippers turned up on her lawn on separate days and she learned the woman next-door didn't have a little girl, the 48-year-old realised the furry criminals had committed their home invasions further afield.
