Yeah they evolved to keep much more baby-like features into adulthood with a big head and huge eyes because that’s cute to us and triggers strong instincts of protection and love. I forget the exact name for it. And my cats do be looking extremely cute all the time so it was very successful.
You can get a cat for who it is more beneficial to stay inside. For example cats who are scared and skittish or cats who are fiv positive. The former should stay inside for their own safety and the latter for other cats’ safety. And they too deserve a home :)
