I got in to Ar Ir's room this evening, and smell some thing bad. Since Ar and Ir some times bring Nowa, one of our cats, to sleep with them; I thought may be Nowa has peed there because the door was closed.
"How could you guys stand this awful smell? Make sure to let your door open if you bring the cats sleep with you"
And Ir replied, "But, Ibu, it wasn't the cat. It was Ar. He didn't pee before bed last night"
