We’ve talked about this before. Cats have whiskers for a reason—to help them navigate in dim light and to guide them in precarious situations. The theory is that a cat uses his whiskers as a guide in entering a narrow passageway so they don’t inadvertently get stuck in a pipe or other too-small space.
Some cats’ whiskers are super sensitive and it bothers them to eat from a bowl, for example. They’re uncomfortable when their whiskers touch the sides of a bowl. We’re advised by experts to feed cats from a plate or a wide bowl.
However, there are always exceptions to a rule. Cats do enter small spaces and get stuck. They get their heads caught in jars and cans and boxes.
