If my cat were to start a diet of Hill's® Prescription Diet® c/d Multicare Urinary Care Stress Cat Food, could this bladder stone break up/dissolve and pass?

I'm sorry to see that Beau has this large bladder stone! The most common types of bladder stones in cats are struvite and calcium oxalate, but the only surefire way to differentiate between the two is with a stone analysis after the stone has been surgically removed. The Hill's C/D multicare can dissolve some struvite stones, but will not dissolve calcium oxalate stones. For the long term, however, this diet is fantastic at preventing a recurrence of such bladder stones and crystals. It's a bit of a gamble using a diet to dissolve stones, particularly in male cats, because of the potential of part of the stone breaking off and causing a urinary obstruction, or blockage, as this is a life-threatening emergency. I generally find it to be safest and most effective to remove bladder stones surgically since you know that it's going to work right away without the same obstruction risks. I hope that everything goes well for Beau!
