They always said Tom and Jerry were really friends, well here's the proof.
The video gives a fly-on-the-wall insight into an unexpectedly intimate relationship between Peanut the rat and its feline housemate.
You would have thought it would be like playing cat and mouse but cat and rat - in this case at least - is a far friendlier game.
Rat loves cat: In this case at least, the relationship has gone far beyond the typical cat and mouse one
Accompanied by a jolly sound-track, the video shows the clearly besotted rat trailing the cat around the house.
To begin with, it seems the rat is a bit of a pest.
At one point, the poor puss leaps up onto the washing basket in a bid to escape the unexpected attention - and Peanut follows.

The rat even shuns his faithful cousin to pursue his usual foe.
But the cat and mouse chase doesn't last long and persistent Peanut slowly wins over its feline friend.
Ranj sprawls out on the mat with his new-found friend climbing all over him.
The victorious rat claws the cat's neck in a playful embrace, licks him and appears to give him a kiss.

The owner wrote about the relationship on the host website: 'Rat loves cat... cat tolerates rat.
'A really cute interspecies relationship My rat, Peanut, follows Ranj around everywhere! She gives him kisses and hugs.'
It's certainly an unexpected union, but it's not the first time animals bonded across the species divide.
And while this pair were clearly brought together in the same home, similar matches have been noted in the wild.
Unlikely bond: Themba the elephant and Albert the sheep
Often, it happens after a young animal who has been weaned becomes attached to an older animal.
Themba the elephant, pictured above, became attached to Albert the sheep after he became orphaned at just 6 months of age.
In other cases, different species connect after the loss of a mate.
'It's amazing what animals do when they want to bond and be close to each other,' Mark Bekoff, a professor of Ecology and Evolutionary Biology at the University of Colorado, told Animal Welfare Institute Quarterly.
