Nursed a dog through something similar 5 years ago with great success. My vet is regular trained and then retrained with Dr. Pitcairn. Best of both worlds as far as I'm concerned. Crystals slice insides of bladdder creating terrible pain and thus constant urge to eliminate. We used vet specialty diet to eliminate (melt) crystals out, dog wore a diaper towards the end as food makes urine terribly dilute. This was for a l20 lb. Akita. Then Thuja. Animal needs to be on a raw diet, preferably no grain component for the time being. Be sure to include Anitra Frazier's "Vita-mineral" mix. Use only muscle meat as it is acidic and organ meat is alkaline, preferably ground chicken or turkey. My cat won't touch beef. Use bone meal and l/8th of a tsp of ascorbic acid. l/4 tsp feline enzyme poweder. Do not feed between meals. Arnika 200 as GM says works great. Aim is to acidify urine as commercial animal feeds are alkaline due to grain component. Cats are carnivores - they don't eat grains naturally. Once a week add l 400 unit vitamin E to help heal scar tissue and contents of a capsule containing l0,000 units vitamina A and 400 units vitamin D to help assimilate the calcium. Use Rescue Remedy every 2 - 4 hours till stones gone. If stones don't show on ultra sound then it's mineral based and cats water must be steam distilled. Eliminate all fish, tuna, dry and semimoist food. give l/2 organic egg yolk in each meal as they are high in Methionine, the acidifying protein. Have done all this with dog and had only 2 recurrences of bladder infection and they were Christmas stress related. My wonderful vet met me at 9:00 on Christmas morning! Now I know what to do. Cat may leak periodically due to scar tissue. But hopefully the peeing will stop. Please neuter when healthy. Vita-Mineral Mix
l.5 cups yeast powder (any)
l/4 cup kep powder
l cup lecithin granules
2 cups wheat bran
2 cups bone meal
Mix and keep all in fridge, always.
Add l tsp per meal. Hope this helps a bit.
