Cat is having litter box issues... Please help.?

..He is still young and although most kittens/cats do this, not all will cover it up..Be grateful he uses the litter and either cover it up yourself or clean it out immediately or both when he is finished and leaves the box..I do this at least 6 times in the run of a day and don't think twice about it because what they give me in return is more than worth it..Make sure you use a clumping litter as well because there usually is no smell at all once covered..Give him time, he may begin to do this or he may not and you will have to get used to covering it up for him, which he will see that it is done next time he goes in and may even start doing it himself.. You can also try relocating the box to a bigger area and see if this works..
