Some animals cannot perspire (sweat) like humans can. When water evaporates it cools the body. Animals, like dogs, open their mouths and exhale water vapor. This has a similar effect as sweating.

Fangs, or canine teeth, in cats may hang out of their mouths due to several reasons, including the shape of their jaw and the size of their teeth. Some cats have a naturally pronounced jaw structure that causes their fangs to protrude, especially when their mouths are relaxed. Additionally, dental issues or missing teeth can also lead to a more noticeable appearance of the fangs. In some cases, it could be a sign of underlying health problems, so it's best to consult a veterinarian if there's concern.
