This indoor lifestyle adds up to a lot of STRESS.
They may not look stressed out sleeping all day in that sunny spot. However, their kitty brains are bored stiff, resulting in stress. Add a neighbor cat or dog coming into their yard, or even a bird or squirrel they can’t chase, and now they are seriously stressed out!
Stress manifests itself through bullying, outright fighting, urination and defecation outside the litter box, spraying, hiding, and excessive grooming (giving them that hairless tummy). Many of these signs are subtle, especially the bullying, and are overlooked by most owners.
