This rings so true. With cats it is almost always the tiny change that gives it away, like eating a little less or sleeping in a different spot, while a dog will usually make it pretty obvious something is wrong. I think that is why cat owners end up watching every little habit so closely.
I completely get this. You check it so often that you start to recognize the usual reviewers and the little back-and-forth, and then one day that small feature you have been hoping for finally lands. It is funny how satisfying something so specific can feel after waiting that long.
