Solved the problem
My elderly cat had issues with food. We feed her wet food in the evening and dry the rest of the time. She would vomit after eating everything. We tried changing her food, cutting down on it but nothing worked until someone recommended Hill's Prescription Food. We still feed her one sachet of wet food a day but the rest of the time she has this or the Dental version (which oddly she seems to prefer). No problems since. Worth the money in my view.
My cat has been on z/d for the last 8years due to food allergies pretty much to every protein possible but suddenly he developed runny diarrhoea/every day.Vet 90%sure is IBD..now in a process to find the right diet and cooking.Nothing to be jealous of.
No more diarrheoa!
Suggested to try this by my vet for potential IBD diagnosis, before going down blood, urine, fecal testing route. It has cleared her up in about a week which is a huge relief. Both cats love the biscuits (nothing was wrong with the other cat but can't feed separately). I'm keeping an eye on the trays as their poop at times is more indicative of constipation but not to a point of concern.
It took a while but my Burmese has almost stopped overgrooming. However, I am wondering if this food is causing her constipation?
I had bought this food for my old cat lady and she very happily devoured it. Unfortunately she has such a strong food allergy that she even had symptoms with the Low Allergen ones that we had to switch to the Ultra Allergen Free food from Hills. However our experience with other cats tells us that it's a super food for cats with sensitive stomachs or allergies.
