My tomcat loved it... before
I don't know what was supposedly "improved" in the recipe, but since the change, the chicken food has become noticeably darker and my cat refuses to eat it at all.
I've tried other varieties too – unfortunately, all for nothing. He just doesn't want to eat the food anymore.
Now I have no choice but to throw away the food I bought. That's not only annoying, but also a pointless waste of money.
It's really a shame that you changed the recipe.
