Dell has offered to replace certain affected models of its Latitude E6430u laptop after customers complained the machine stunk of cat urine. The return program was initiated after laptop buyers took their grievances to Dell’s support forums, expressing disgust — and no small amount of confusion — over their new computer’s scent.

A Dell customer, going by the name of “three west,” first reported the malodorous defect to Dell’s support website in June 2013. “the machine is great,” posted the disappointed buyer,  ”but it smells as if it was assembled near a tomcat’s litter box. It is truly awful! It seems to be coming from the keyboard.”

Since then, the computer maker’s forums have been flooded by buyers with similar stories.

“Well .. here I am Sunday doing some work on the couch and my wife says ,’What stinks like cat pee?’” recounted one user. “I said … I think its this laptop … she puts her nose up to the keyboard and BAM! It really stinks’.”
