My cat has been on royal canin sensitivity control for a long time due to runny poos. The vet said it was ok to keep her on this. I’ve tried her on another food (Harringtons) for a couple of weeks to try and save money but she has the same problem again. Has anyone tried any other foods that are good for sensitive tummies but may not cost quite as much? I’ll obviously pay if I need to, but as a single mum things are getting very tight so trying to find alternatives for everything.
