Causes
Multifactorial, strongly linked to stress (changes at home, conflict with other cats, boredom). Contributing factors: overweight, sedentary lifestyle, low water intake, unsuitable litter tray.
Diagnosis
The vet rules out infection, crystals and stones (urine analysis, ultrasound). It is a diagnosis of exclusion.
Treatment
Reducing stress is key (environmental enrichment, pheromones, more litter trays). Increase water intake (wet food, water fountains). Pain control during flare-ups. If there is an OBSTRUCTION, it is an emergency: it must be relieved immediately.
Prevention
Reduce stress, wet food, water fountains, enough clean litter trays (the N+1 rule), a healthy weight, daily play.
