Hello, it seems to me that there is something wrong with the dry cat food mentioned above! As always, my 4 Büsis loved this dry food without any problems. Yesterday 3.2.18 I bought another bag and opened it this morning 4.2.18 to feed them. Funnily enough, all 4 of them have been regurgitating the food independently of each other ever since! They keep eating it hungrily throughout the day, but it doesn't take them an hour to vomit it all up again! This seems a bit strange to me right now! Now I'm going to put the food away so that they can't eat any more of it and I'm wondering whether I should take the bag of food I've started back to the Migros store? Would be grateful for clarification and an answer!
