We’ve recently moved from Central Europe to UK with our cat. He has issues with struvite crystals in his bladder and I’ve just discovered that his long term medication (Urinovet Cat Dilution) isn’t available in UK. I’ve managed to get him the Calm Urofel, but not the Urinovet. My vet in Europe said it is a supplement, not a prescription medication, and didn’t know what might replace it here. Are there any vets here who can advise? Obviously we will take him to the vet here, but after his long and traumatic journey, I wanted to wait for a bit before taking him to the vet. DL methionine appears to be the active ingredient.
