Lower urinary tract signs can create barriers between cats and their pet parents. Not only is it stressful and painful for cats, it also impacts their owners. With a multimodal approach including the right nutrition and environmental enrichment, you can help you patient get back to their day to day life.
Some feline urinary fast facts:
- Overweight and obese cats have 1.6 times higher prevalence of feline lower urinary tract disease (FLUTD) than lean cats1
- Feline Idiopathic Cystitis (FIC) is the most common cause of FLUTD, representing 60%, nearly 2/3, of all cases2-5
- Stress is a major risk factor for FIC. Uroliths are the 2nd most common cause of FLUTD (20% of cases)2-5
- Struvite and calcium oxalate (CaOx) and are the two most common urolith types in cats6
How does nutrition help with FIC?
Stress is postulated to play an important role in the development of FIC, and stress reduction is recommended as a key component of multimodal management for these cats. L-Tryptophan and milk protein hydrolysate (also known as hydrolysed casein) have been shown to decrease anxiety and stress-related behavioural signs and may be helpful for cats with FIC.7,8 Foods containing these ingredients, such as Hill’s c/d Stress for cats and Metabolic + Urinary Stress, can play an important role in the management of cats with FIC. Moreover, Hill’s Prescription Diet c/d Multicare cats has been clinically proven to reduce the recurrence of episodes of FIC by 89% through enrichment with n-3 fatty acids from fish oil and antioxidants.9
In recognition of the increased incidence of FLUTD in overweight and obese cats Hill’s has combined the proven technology of Metabolic & c/d Multicare Stress Feline to help manage overweight and obese cats with common feline urinary disorders.

How do you manage your feline struvite urolith cases? Jump to cut? Or try food first?
If you are inclined to jump in to remove suspected struvite uroliths surgically, perhaps you should take a look at The American College of Veterinary Internal Medicine (ACVIM) consensus statement on urolith management. This is an excellent resource that outlines several recommendations and standards of care for dogs and cats with lower urinary tract uroliths. One key ACVIM recommendation is that uroliths consistent with a composition of struvite should be medically dissolved.12 This is particularly relevant for feline urolith cases as they are almost always sterile, and thus are relatively quick and easy to dissolve with dietary management. Our general advice to veterinarians for suspected feline struvite uroliths is to re-X-ray (or scan) two weeks after starting any one of our three Prescription Diet Feline Urinary foods for dissolution. If the stone/s is struvite then it should be reduced in size or density by 50% or completely gone at the 14 day mark.
Urinary issues require lifelong care to manage and minimise future recurrences. For a full suite of pet parent communication tools contact your Hill’s Territory Manager.
