I was recently reminded, at the cost of $300 for a vet visit, that dry cat food is convenient, but not conventional. My male cat Sterling Merlin was urinating blood. An ultrasound showed he had a bladder stone. Had we not caught this in time the cost could either have been his life or $1000 for surgery, at least. So now he’s only eating wet food and Primal Pet raw food, allowing him to eat more naturally, as cats in their natural state were not meant to eat dry kibble. I’m also giving him Udo’s supplements and the Chinese herb Passwan, which helps dissolve urinary stones. Male cats are more susceptible than female cats to bladder problems due to cat kibble, however females are not excluded.
