Buspirone for Cats in 2025: Vet-Approved Guide to Urine Marking & Anxiety Relief 🐱💊🧠

By Dr Duncan Houston

💡 Buspirone is a trusted option for treating feline anxiety and urine marking without the sedation or dependency risks of traditional tranquilizers. As of 2025, it remains a cornerstone for managing stress-related behaviors in cats using a gentle, serotonin-based approach.

🔬 What is Buspirone?

Buspirone is an anxiolytic (anti-anxiety medication) from the azapirone class. Unlike benzodiazepines like diazepam, it has no sedative, muscle relaxant, or addictive properties. Its action is focused on serotonin 1A receptors in the brain, promoting calmness without sedation.

📌 Common Veterinary Uses in Cats

• 🚽 Stress-related urine marking (especially indoor spraying)
• 😿 Social anxiety in timid or submissive cats
• 😾 Tension in multi-cat households (bullying or withdrawal)

💊 How Buspirone is Administered

• Available in 5, 7.5, 10, 15, and 30 mg tablets
• Typically given 2–3 times per day
• Can be given with or without food
• Requires several weeks of consistent use to take effect

📈 Treatment Timeline & Expectations

🧠 Final Thoughts from Dr Duncan Houston

Buspirone continues to be a valuable behavioral tool in 2025—especially for urine marking and general anxiety. It’s non-sedating, non-addictive, and often solves stress behaviors that frustrate pet owners. When paired with environmental adjustments and the Ask A Vet app, success rates rise even further.
