Welcome to Pet Talk and I'm so sorry to hear about Tinkerbelle. I have 4 male cats and two of them have had blockage due to crystals. Cirrus required surgery and Storm is now on a special diet. They're on the Hills Presription c/d diet which is supposed to help both struvite and calcium oxalate crystals. I'm also going to be putting my other two cats on this as a preventative measure. So far both Storm and Cirrus have been doing well.

I'm not sure what kind of advice to give you because I haven't experienced these kind of symptoms before. Maybe the new food just doesn't agree with her tummy. You may need to end up taking her to the emergency vet again because you don't want her to become dehydrated. Try to force some water down her throat with a syringe if you can and watch her. If she continues to vomit then please take her to the emergency vet. She may have other problems going on that you're unaware of. Good luck and please keep us updated.
