For some reason I've always had it in my head that kittens should be fed on only one or two foods, no snacks or treats or variety for at least their first six months (or longer), to help prevent finickiness, and so I have been advising people.
But on giving it some thought I realized that my two current cats whom I rescued in tiny babyhood (one is 12, one is 1) are both frustratingly finicky, whereas the two who were rescued as adults are not, and I have no idea what they ate in their formative year.
So, is that coincidence? Are cats either born finicky or not finicky? Or did I create their finickiness?
