My cat is having trouble using the litter box she is sixteen years old. She has defecated tho' only about twice very little hard stools. I believe she is still able to urinate. However she goes in and out of the litter box and just sits there. Sometimes I notice she is outside the litter box doing what appears to be trying to go outside of it tho' still nothing. I put a teaspoon of mineral oil in wet food and wondered if that is safe ? It is not really helping. I also tried some lactose free milk.
