How long does a cat’s urethritis take to heal?

Feline urethritis usually takes 1-2 weeks to cure, with the time depending on the cat’s constitution, cause, and severity. Causes include stones, parasites, and bacteria, most often bacterial. Bacterial urethritis generally needs about 7 days; if severe, the period lengthens, and the owner must keep medicating and caring under the vet’s guidance.
