I have a male kitten 14 weeks old and he seemed to of “dribbled” on the sofa. This is a first he is usually so good with the litter tray not an accident yet. It smells really strong!! how do I get this out without ruining the sofa? I have steamed it and still waiting for that to dry I’m just worried that the more I was to scrub the more you will see it as it’s a very light grey sofa. Suggestions would be really appreciated.
