A proper litterbox set up is key to a healthy, happy cat.
Litterboxes are a nuisance to us humans. They are arguably the worst part of cat ownership, which often leads to them being put in the corner of laundry room and forgotten.
To cats however, litterboxes are an extremely important resource. A litterbox that is always dirty, too small or is shared between several cats, is just not appealing to most kitties, which is why inappropriate urination (peeing outside the litterbox) is the number one behaviour problem seen in our feline friends.
It is extremely important that we, as cat owners and lovers, respect our cats need for a proper litterbox setup and daily maintenance.
