My little guy has FLUTD, and though he has only suffered from a complete blockage once, he gets irritated from time to time. His litter box is always cleaned daily, he's an indoor cat, currently has lost a bunch of weight, and has special food and glucosamine for his urinary problems. Currently, I'm treating him for a urinary tract infection and I wanted to know if it's because of his FLUTD or if it was possibly just me worrying too much.
