Hi Willy. I hope that you'll start feeling better soon. Storm knows all about UTI's but he says it's much better than having crystals or being blocked which he has also deal with. He's my largest cat at 13.9lbs and he can't even imagine you at 16.8lbs. He agrees that a diet is in order. Maybe your 2 foster kittens can help you play more and take off some of the extra weight. Storm's younger siblings keep him in shape but he also doesn't get free fed which has helped everyone around here. Get well soon big boy.
