Male cat refusing to use litter
I have a 3 year old neutered male, for the last 2 years he has been going to the toilet outside but in the last month he has been pooing and weeing in one particular place in the house, he has a cat door to go outside but we didn't have a litter inside, I have now put a litter inside but he refuses to use it. Not sure about this but I was thinking of placing the litter in the place that he always goes and then slowly moving it back into the laundry were we want him to use it.
I could really use your advice.
