Hi thank you very much for all the answers,specially xena and caliph.Kids should be thought to take care of the pet as well as not to be inconciderate to other people.I was in a situation where I have to jump over the litter tray where it scattered all over every morning.And they only clean it rarely.It is a disrespect to the kitten(ohh forget about the tenants).Good news is I managed to move the kitten in to their apartment so that they all can live happily ever after.
