The Question
“Hi there Dr Paola,
Our calico cat Louise has taken to licking walls, faux-wooden doors, and whatever else happens to be nearby. I am concerned both about this odd behavior and its potential impact on her health. Please advise!”

Quick Info about Louise
Dear Nancy,
Louise’s behavior may look quirky, but persistent licking of walls, doors, or other household surfaces can sometimes point to an underlying issue worth investigating. Cats may develop repetitive licking behaviors from stress, anxiety, boredom, gastrointestinal discomfort, nausea, dental disease, or, less commonly, neurologic conditions. Some cats also become very focused on textures or residues on surfaces, especially if cleaning products, cooking oils, or dust are present.
Because household surfaces may contain chemicals, paint residues, adhesives, or splinters, it is best not to ignore the habit. A veterinary examination is important if Louise is licking daily, swallowing non-food material, vomiting, drooling, losing weight, or showing changes in appetite or behavior. In the meantime, increasing enrichment can help. Interactive play, food puzzles, climbing spaces, and predictable routines often reduce repetitive behaviors in cats. Cleaning surfaces with pet-safe products and redirecting her toward safe oral activities, such as dental treats or textured cat toys, may also decrease the urge to lick inappropriate objects.
I hope this helps!
