Our cat had continually bubbles problems. Always at the vet and then even veterinary clinic. Suspected cystitis with Kristalen in the bladder. On doctor's advice, we have this dry food bestellt.Schnelle delivery and packaging was also on. Our cat liked it and now after 3 months use of the product is everything properly, are relieved to finally have animals also hurt. He has recovered well and may all fressen.danke again
