As cats get older they may start to change their behavior or even develop what we see as cat behavior problems. But with the right diagnosis, treatment and some patience many of these problems can be resolved.
Urinating or defecating outside of the litter box is one of the main behavioral problems in elder cats. There are many possible reasons for this, including a possible medical condition. It is important to have your cat checked by her veterinarian in case there is a medical condition causing the litter box problems. Diagnosis and treating a health condition can help stop the litter box problems, or help you make adjustments in your home that may help curb the problem.
Pay close attention to her habits to watch for changes in these habits. You may need to move or add a litter box to make it more convenient for an aging and possibly arthritic cat.
