'Not only did he eat plaice, flounder and flatfish, he also tore packages with dried octopus and other seafood delicacies,' complained Irina Kuzmina, the owner of the shop. A video of the cat has gone viral. Airport security are unsure how the ginger cat sneaked into the terminal.

'Of course, we had to write off all the products that were in that shop window,' Irina said. 'The food will be dumped. We have also disinfected and cleaned the shop window. All in all, the kitty put us out of pocket as products worth 60,000 rubles have been wasted.'

An airport spokesman said: 'Pets are banned from being kept at the airport due to safety regulations.

'There are also contracts and agreements with cleaning companies which make it impossible for stray animals to get inside the terminal.

'We do have a number of passengers travelling with their pets, so perhaps one of them escaped.

'As of now it is not clear how the cat made its way to the shop window'.
