why is my cat peeing on things?

Inappropriate urination, or periuria, in cats is a common and concerning issue that requires prompt investigation. The primary step is always to rule out underlying medical conditions. Feline Lower Urinary Tract Disease (FLUTD), which encompasses conditions like urinary tract infections (UTIs), bladder stones, crystals in the urine, or idiopathic cystitis (inflammation without an identifiable cause), is a frequent culprit. These conditions cause discomfort or pain, leading cats to associate their litter box with negative experiences and seek alternative, often softer or more absorbent, places to urinate.

If medical causes are ruled out by a veterinarian, behavioral factors are likely. Stress and anxiety are significant triggers; changes in the home environment, new pets, visitors, or even changes in routine can cause a cat to feel insecure and urinate outside the box. Litter box aversion is another common reason, often stemming from an unclean box, the wrong type of litter, an insufficient number of boxes (ideally one per cat plus one extra), or an undesirable location (e.g., noisy, high-traffic areas). Territorial marking, particularly in unneutered males, is also a possibility. A veterinary visit is crucial to diagnose the root cause and establish an effective treatment plan.
