Smiling is a human construct and not a natural part of the animal kingdom. This is probably why we enjoy it so much when we think cats are actually smiling because it’s out of the ordinary.
Although your kitty may not be able to physically “smile” exactly like a person, that definitely doesn’t mean she doesn’t have her own ways to express joy. I do believe cats can show happiness in their eyes, but it’s not obvious to see. Cats are highly emotional creatures, and the better equipped you are to understand her feelings.
