There are a few reasons why Harley and Marley may be urinating outside their litter box. Certainly things like a urinary tract infection are possible. Crystals in the urine are another reason this could occur. I would recommend to make an appointment with their vet to have their urine tested for infection/crystals. Behavioral issues are another reason for not using the litter box. Changes in the type of litter, the litter box itself or the location of the box can all effect behavior. The litter box needs to be cleaned daily. In general, cats prefer a clay based clumping litter in a large, uncovered litter box. They also want the box in a quiet and private location. Cats do not want to be cornered in the box by other cats or dogs so make sure it feels safe for the kittens. Lastly, adding a second or even third litter box can help. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
