"In general, it is a very good thing for animals to sleep with their people," said Dr. Dana Varble, the chief veterinary officer for the North American Veterinary Community.

"Do you really think there's enough room for you?" -- Delilah, a 10-year-old Siberian husky.

"In the animal world, animals who are bonded tend to sleep together," Varble said.

Dogs and cats who share their human's bed tend to have a "higher trust level and a tighter bond with the humans that are in their lives. It's a big display of trust on their part," Varble said.

"When a dog turns their back to you, it's an incredible sign of trust because that is a very vulnerable position for them -- they can't keep watch for danger," Varble said.

"Dogs and cats who are more closely bonded with their humans get additional health benefits," Varble said, including increases in oxytocin and dopamine, the feel-good hormones.

"What? I don't snore!" -- Luna, a 2-year-old Siberian Forest cat.

"Make sure all the pets in your house are up to date on flea, tick and internal parasite prevention, especially if you're going to have them in your bed," Varble advised.

"Animals have different personalities like we do," Varble said. "Some people sleep with the lights on and some people like to sleep in the complete dark. One pet might have more of a protective, another more of an assertive personality."

A dog who sleeps at the end of the bed with their face toward the door might have a more protective personality, Varble said.

"Thank goodness that bed hog Beast is gone so I can catch up on my zzz's." -- Buttercup, a 4-year-old beagle-bulldog mix.

"I may look like an angel, but in the night I have been known to walk or sit on my humans and try to smell their breath. I also enjoy draping my 2-foot-long body across their necks at about 3 a.m." -- Lynx, a 2-year-old Siberian Forest cat. Sandee LaMotte/CNN
