There are times when your cat may eliminate outside the litter box. One of the most common issues is a dirty, stinky box. If the litter box stinks, your cat will find a less appropriate place to go. New household members or disruptions to the household such as guests or construction workers may cause your cat stress. She may become nervous about going to the litter box. You need to set up a clear path to the box away from these stressful forces. Or you may want to temporarily set up another box that is easier to get to. As your cat ages, she may develop some mobility issues. Check that your cat can get in and out of her litter box with ease. However, a sudden lapse in using the litter box could indicate a medical issue. Make an appointment with your Greenville, SC veterinarian for evaluation and treatment.
