And cat Micky (had to stay at the shelter for a long time before he again found a home), unfortunately, with its nine cats years, equal to both diseases. The special feed "Urinary S / O" by Royal Canin, is recommended in this case by vets who sell it. I have it ordered from Amazon, because delivery is made directly into the house.
If the cat or - most often - the cat has not been set at this high fiber diet, but you should better anticipate consult a veterinarian, so that one, bringing the day-feed ration depends on weight and condition of the animal in experience and whether these feeding alone is sufficient in a diseased animal; so must hangover Micky swallow an additional heart tablet example yet.
I used my cat, who has tended quite young to urinary stones, which in many castrated males is actually the case, as a precaution fed once a day "Urinary" (on the advice of a veterinarian out), and that has proved itself very well.
Some cats are real "dry food fans", but if an animal Nassfutter preferred so there is Royal Canin also because the product involved.
