My parents' 12 year old cat has a new habit. She has decided to not cover her poop in the litter box. This has been going on for 3 months now. She has been using the same brand of litter all her life (clay). They took her to several pets to get her checked out for any medical problems but none of them could find anything wrong with her and actually she is in perfect health.
So I am doing what any logical person would do and ask here on PA for help. Any ideas? This is a concern because her litter box is in the bathroom and her poop stinks.
