My cat suffers unfortunately on stones in the bladder, which keep coming back. These stones are caused by dry food and canned food. Again and again I found blood from my tomcat urine. Since I use the Urinary, he had nothing more !! What's more, I can also feed quiet times wet food because the Urinary is also preventive !! So great food, I can only recommend to anyone who has the same problem with his cat !!
