Overview
Feline Lower Urinary Tract Disease (FLUTD) encompasses several conditions including bladder stones, urethral blockage, and interstitial cystitis. In dogs, urinary stones and infections are common. Diet plays a crucial role — the mineral content, pH, and water content of food directly affect stone formation. Male cats are especially at risk for life-threatening urethral blockage.
Symptoms to Watch For
- Straining to urinate or crying in the litter box
- Blood in urine
- Urinating outside the litter box (cats)
- Frequent urination in small amounts
- Licking the genital area excessively
How Nutrition Helps
Urinary health diets manage mineral levels (especially magnesium, calcium, and phosphorus) to prevent crystal formation. Wet food is strongly recommended as increased water intake dilutes urine and reduces stone risk. Controlled pH prevents both struvite (alkaline) and calcium oxalate (acidic) stones. For cats with FLUTD, switching from dry to wet food alone can reduce recurrence by 50%.
How Activity Helps
Reducing stress is key for cats with idiopathic cystitis. Environmental enrichment, regular play, and a calm household help prevent stress-related flare-ups.
Prevention Tips
- Feed wet food or add water to dry food
- Ensure multiple clean water sources
- Provide enough litter boxes (cats + 1)
- Reduce stress with environmental enrichment
- Annual urinalysis for predisposed breeds
Breeds at Higher Risk
Persian and Himalayan cats, Dalmatians (urate stones), Miniature Schnauzers, Bichon Frises, and Shih Tzus in dogs.
