Batch-related rejection
My cats used to love this variety. But from a certain batch onwards, suddenly neither of them would touch it anymore. Unfortunately, this also happens with other varieties. According to Petsnature, this is due to variations in raw materials. Sadly, it affects both cats the same way, which is strange.
There are also differences in colour and consistency, even with the new recipes. Because of allergies, only a few varieties can be fed. These variations make it even more difficult.
