Everyone knows the internet is all about cats, but Dell may have taken that too literally with one of its new computers.

The company this week issued one of the funniest customer service notes in the world of tech when it offered to replace a part in laptops that smell like cat urine.

Dell Latitude 6430u: Users have complained it smells like cat urine.

For months users have taken to Dell's community forum to complain that the Dell Latitude 6430u laptop smells like it was assembled near a litter box. Many in the thread point out that they have had to apologise to their clients when they take out their laptop in front of them while others expressed their frustration with Dell because they have scolded their cats for the odour.

"I have been blaming a new kitten who I swore was creeping into my closed back pack at night and magically only hitting the PC with a concentrated urine stream which then magically evaporated," one user said. "Glad to hear I am not alone (people see me smelling my PC and think I am insane!) and my apologies to the cat."
