For cats with lower urinary tract signs, changing their food can change their world Hill’s® Pet Nutrition Prescription Diet® c/d®

Multicare is the only clinically tested food that dissolves struvite stones in as little as 7 days and reduces the rate of recurrent episodes of feline idiopathic cystitis signs by 89 percent

TOPEKA, Kan. (Oct. 14, 2013) – Signs of feline lower urinary tract disease are frequently encountered by veterinary health care teams. Now there is a single nutritional solution that has been clinically tested to dissolve struvite stones in as little as seven days and also reduce the rate of recurrent episodes of feline idiopathic cystitis (FIC) signs by 89 percent.

New research published in this week’s issue of the Journal of the American Veterinary Medical Association establishes Hill’s® Prescription Diet® c/d® Multicare as the only food clinically tested to dissolve struvite uroliths in as little as seven days (average 28 days in vivo study in urolith forming cats).1 Additional research has proven the effectiveness of c/d® Multicare for decreasing the rate of recurrent episodes of FIC signs during a 1-year clinical study.2 And, feeding c/d® Multicare results in the production of urine that is undersaturated for calcium oxalate and struvite, which decreases the risk for recurrence of the two most common urolith types in cats.3

Results of the first controlled clinical trial to determine if dry therapeutic foods can dissolve struvite uroliths indicate that c/d® Multicare can reduce urolith size by 50 percent in as little as five days and, in some cases, completely dissolve the stones in as little as seven days.

“Nutritional dissolution with c/d® Multicare has been shown to be rapid, safe and effective,” said Jody Lulich, DVM, PhD, DACVIM, of the Minnesota Urolith Center at the University of Minnesota College of Veterinary Medicine, and lead author of the study.

In some cases, surgery may be necessary, but the majority of cats with disorders affecting the lower urinary tract can be managed with a multimodal approach consisting of therapeutic nutritional changes and steps to reduce stress, including environmental enrichment. 

"Nutritional dissolution is the compassionate choice for managing struvite uroliths,” Lulich said. “Some veterinarians prefer to remove uroliths surgically due to the perception that surgical management is more effective, but that is not always the case. Medical dissolution of sterile struvite uroliths is more effective than surgery, and is not associated with increased discomfort or urethral obstruction.”

Beyond dissolution, c/d® Multicare can be used as a maintenance food that has been clinically tested to reduce the rate of recurrent episodes of FIC signs and is appropriate for healthy cats in multi-cat households. In a separate, 12-month clinical study, consistent feeding of c/d® Multicare to cats with FIC reduced the rate of recurrence of episodes of FIC signs by 89 percent.


Hill’s Prescription Diet c/d® Multicare is the Single Solution for Urinary Health

“Before now, no treatment had been demonstrated to be consistently effective for management and prevention of FIC signs. This study definitively shows that the nutritional profiles of food impact the expression of acute FIC signs in cats,” said John Kruger DVM, PhD, ACVIM, director of the Center for Feline Health and Well-Being at Michigan State University's Veterinary Teaching Hospital, and lead author of the study.

Diagnosing FLUTD: Watch the Signs

If a feline patient exhibits signs of FLUTD, a veterinarian should evaluate the cat and perform a urinalysis and diagnostic imaging when appropriate. Based on the result, c/d® Multicare can then be used to eliminate struvite uroliths in the case of struvite urolithiasis and to aid long-term prevention of recurrence in the case of FIC and struvite and calcium oxalate stones.

Health care team members may also send uroliths to the University of Minnesota Urolith Center for quantitative analysis. After analysis, it is essential to monitor the cat’s progress and emphasize the importance of continuing nutritional management with c/d Multicare.
