Cat not using litter tay at night

What can I do about Cat diahrea and elimination of this outside the box? This occurance takes place in the same room of the box and only at night, I provide a cleaned box three times daily.

Hi
well there are two issues here. Firstly if it is diarrhea then the pooping outside the box is caused by an illness and is not behavioral. In which case the diarrhea needs to be treated. please see my web page about this here

however if it continues then a trip to the vet would be a good idea.

if it is not diarrhea but simply the cat going outside of their box then it is behavioral and can have many causes. please see my web page here about this issue
