Since starting our cat on this product we haven't had one more emergency vet visit. Highly recommend and the vet shed always manages to have it in stock so we never run out

All good packed very well and came on time

My female cats were constantly suffering from urinary tract infections and it was costing me a fortune each time at the vet. My vet recommended I start them on this product, together with the urinary wet sachets. My cats have been on this diet for approximately 2 years and have not suffered a UTI since. This product is worth every cent!

The cats like it and has worked for urinary health

Our girl cat had a a few bouts of urinary problems but since starting on these biscuits, she has not had any symptoms since. The VetShed are superb in terms of communication and delivery - highly recommended.
