Hello, We have a 2 year old female British Shorthair Cat, diagnosed and receiving treatment for struvite crystals. We've always fed her a combination of dry (Acana Wild Prairie / Acana Grasslands) and wet food (home cooked recipe, no store bought). However, since we moved country which was about 6 months ago, we didn't have the means and time to cook her wet food ourselves anymore, so after experimenting with various store bought wet food satchels, we settled for Whiskas. As for dry food, we switched her from Acana to Royal Canin's British Shorthair Food as we noticed she liked it better and instantly devours it, unlike the Acana one which lingered in her bowl throughout the day. We also supply enough fresh water daily which she drinks as far as we've noticed. The point of this thread I guess is to try and have a better understanding of the connection between cat food and these struvite crystals, because we suspect these crystals started forming after we've moved country and switched her to Royal Canin (dry) + Whiskas (wet). Are there any ingredients in store bought cat food that as far as you know can lead to struvite crystals formation? I've read posts saying that grains and cereals in dry cat food are bad, but I've looked up the ingredient list of the Hill's c/d dry food which the vet prescribed for this ailment and that also has them, so I'm unsure what diet to put her on. Anyway, any tips from your personal experience are welcome.
