No, cats' eyes typically do not stay open during anesthesia.
Anesthesia works by suppressing the central nervous system, which includes the muscles responsible for keeping the eyes open.
This means that a cat's eyes will close naturally during anesthesia, just like they would when they are sleeping.
However, it's important to note that some cats may have their eyes taped shut during surgery to prevent them from drying out.
This is a common practice and is generally considered safe.
If you have any concerns about your cat's eyes during anesthesia, you should speak to your veterinarian.
