Babysitting my mom’s three cats. She left a box of Churu. They like them a lot. I was surprised. I thought it was just a few rare internet videos I have watched. Cats really like this.
My cats actually prefer Delectables over Churu (they tell me it's a consistency/texture thing). But I think both brands have some form of bone marrow in them to make them extra umami. Not nip. Could be why your nip-resistant kitties still lose their minds over Churu.
