I guess I just haven't had this experience with cats. Mine is always excited to be fed the same dry food every day. For some reason she prefers dry over wet, and the rejection of the wet food only happened once before I made the switch. Why feed your cat food they don't like?

No, this is not how cat are. The internet has a different headcanon because people usually misinterpret them and create memes and videos based on that. They'll either expect dog behavior or misattribute human intention. Cats have a completely different body language.

I encourage everyone watch real cat behavior videos and observe cats closely and without judgement.

What kind of bowl do you use? And do you have their water near the food bowl? Cats usually dislike bowls that are small enough that they hit their whiskers on the sides when they bend down and sometimes they don't like to eat where they drink (something in their evolutionary background tells them that it's unsanitary or something).

Of course, cats can also just be picky eaters and get tired of the food. That's also pretty common.
