My female cat has blood in her urine, how long will the antibiotics she was prescribed need to take effect?

Hello there,



I'm glad you reached out with your concern about your cat. Seeing blood in your cat’s urine can be alarming, but it's a good first step to have her on antibiotics, as bladder infections are a common cause. Typically, you should start seeing an improvement in her symptoms within 48 to 72 hours after starting the medication.



Besides a bladder infection, other potential causes include urinary tract stones, stress-induced cystitis, or more rarely, tumors. In the meantime, ensure she has easy access to fresh, clean water to encourage her to drink often—hydration can help flush out her bladder. You might also consider offering wet food to increase her fluid intake.



Keep a close watch on her behavior over the next few days. If she seems to be in pain, is straining to urinate, has a reduced appetite, or if you notice a change in her normal habits, a more urgent issue could be at hand. It’s important to monitor the situation closely.
