Royal Canin Urinary S/O High Dilution UHD 34 is a complete food for adult cats. It has been specifically developed for cats with struvite and calcium oxalate urolithiasis and to help to dissolve struvite uroliths. It is also suitable for cats with lower urinary tract diseases. The food acidifies the urine which will dissolve struvite stones and will help to prevent them from reoccurring. It also has a low level of magnesium which is a component of struvite crystals. This will help to prevent their formation.

 Royal Canin veterinary dients should only be given in conjunction with your vets recommendation!

If we cannot do so within 3 working days we will contact you by email.

Delivery of aerosols

Due to restrictions aerosols can't be sent by Royal Mail. We appreciate your understanding.

Delivery of temperature controlled items

Some products, such as insulin and frozen food, need to be delivered in insulated packaging to prevent them from getting too warm (or too cold) during transit from us to you. Purchasing any of these items in your order will result in a £1.99 charge being added to the total to cover the high cost of the insulated packaging materials. You only pay the £1.99 once per order, regardless of how many temperature controlled items you purchase in that order.
