Urinary & Litter Box Guide
Litter box changes are one of the earliest signals your Cat’s body sends.
Changes in frequency, output, location, or avoidance can reflect anything from a stress response to a life-threatening obstruction. Know what to watch for.
Emergency, A Blocked Cat Cannot Wait
Repeatedly going to the litter box with little or no urine output
Crying or vocalizing in the litter box area
Straining with nothing coming out
Excessive licking at the genital area
Lethargy alongside litter box changes. A male Cat who cannot urinate can deteriorate within hours.

Common Causes
What your vet will consider before the exam begins.
Very Common
Feline Idiopathic Cystitis (FIC)
The most common urinary presentation in Cats. Often triggered by stress. Signs mimic infection but no bacteria are present. Management is behavioral and environmental as much as medical.
Cats 7+
Urinary Tract Infection
Common in older cats and those with diabetes. Requires urinalysis and culture for diagnosis. Often a secondary condition in Cats with other underlying disease rather than a primary infection.
Requires Imaging
Bladder Stones
Mineral accumulations causing irritation or partial obstruction. Detected on X-ray or ultrasound. Diet and, in some cases, surgery are the primary management approaches.
Emergency — Males
Urinary Obstruction
Partial or complete blockage of the urethra, most common in male Cats. Rapidly life-threatening. If your male Cat is straining with no output, this is a medical emergency.
Behavioral
Litter Box Aversion
Elimination outside the box is communication. Aversion can result from cleanliness, litter substrate, location, painful elimination history, or multi-Cat tension.
Early Detection Critical
Early Kidney Disease
Increased urination combined with increased drinking is among the earliest behavioral signs of chronic kidney disease (CKD). Reporting this change promptly allows for early intervention.
What to Track Before Your Visit
The history you bring shapes the diagnosis.
✓
When did you first notice the change in litter box behavior?
✓
Going more often, less often, or apparently unable to go?
✓
Normal urine output, small amounts, or none visible?
✓
Any blood visible in urine or on the litter? A photo is helpful.
✓
Vocalizing, crying, or distressed in or around the litter box?
✓
Using the box outside its normal location, or eliminating elsewhere?
✓
Any recent changes in environment, routine, or household?
✓
Current diet: dry food, wet food, water fountain or bowl

A Note on Hydration
Cats evolved from desert animals with a naturally low thirst drive. Dry-food-only diets consistently produce lower daily water intake. Chronic mild dehydration is a significant contributor to urinary disease in Cats. This conversation is worth having at your visit.
Urine Samples
At CatsOnly, we prefer to obtain urine via cystocentesis in clinic, a clean sample directly from the bladder that gives us the most accurate results. There is no need for you to collect a sample at home.
