Verified Purchase

Poppy has been on this prescribed dry food for approximately 4 years. She enjoys it, thankfully, as her condition doesn't allow her to eat any other dry cat food. The fast delivery of the item was greatly appreciated.

Light crystal management cat biscuits
Verified Purchase

By Kim Daniel on 12 April 2023

Excellent dry cat food for pets suffering with urine problems... We now use crystal light as we found out cat putting too much weight on so the light management of this product is better if your cat has weight issues. My cat Pippin loves this product and would not use anything else.
Thankyou 🐱

Can this food be used as a cat's normal, year-round food or should it just be used temporarily to reduce crystals?

  • VioVet Staff

This is a complete die that can be used in the long term but only alongside veterinary advice. Whether it is appropriate for long term use is best determined by your local vet.
