We have 2 cats about 4 years old. We got them both at the same time when they were about 8 weeks old.

They are shut in the laundry room at night and their food, water, beds and litterbox are there. I have arthritis and am afraid of falling over them at night if I get up. The litterbox is in a separate area between the washing machine and a wall.

They have always shared the litter box with no problems. In the last few weeks, and not every morning but on several occasions, one of them (we don't know which one) has urinated just in front of the litterbox or on the rubber mat that is supposed to stop tracking.

We use clumping litter. The box is sifted morning and evening. Once a week the box is cleaned completely and once a month it is cleaned and brand new litter is put in.

Nothing has changed in the way we deal with their litterbox in 4 years.

Why might this be happening? Is there anything we can do to stop it?
