Wondering if your pet rat is feeling happy? You should check its ears, researchers say. A team of scientists in Switzerland found that a rat's ears are more pinkish and are positioned at a more relaxed angle when it is experiencing positive emotions.
If they urinate or defecate when they're in a new place, it means they're frightened or distressed - if this happens, return them to their familiar home-cage. Different rats behave differently in similar situations, as they each have different personalities and may have been reared differently.
Whistling or chirping: Rats may make high-pitched whistling or chirping sounds when they are happy or excited. Growling or grunting: Rats may growl or grunt when they feel threatened or aggressive.
Most pet parents notice bruxing when the rat is happy and showing signs of affection—similar to a cat purring. However, rats may also brux when they are stressed. Make sure to take the rat's entire demeanor and behavior into account when they brux.
Sometimes rats like to feel things with their teeth. A good example of this would be if you stick your hand in their cage, and then they start to lightly nibble on your fingers. This behavior is just them exploring the new thing; they aren't trying to hurt you at all.

Rats make lifelong bonds with their owners Ask any rat owner, and he or she will tell you: Rats recognize their owners and respond to their sight and voice. They are very social and love to hang out with human family members on the couch or on peoples' shoulders or in their laps.
Dogs have “puppy eyes,” but rats are just as gifted at looking pitiful to get your attention. You've probably noticed your rats hovering at the cage door, staring at you with pleading eyes. Whether they are begging to be fed, let out to play, or looking for a snuggle, this is a sure sign they want your attention.
If your rat nibbles or licks you, he or she might be showing you affection by grooming you. Rats also have an excellent sense of smell, so your rat might nibble or lick your hand or smell you after you eat or prepare food.
The past decade dramatically deepened our understanding of the biological origin of this capacity. We now understand that rodents robustly show emotional contagion for the distress of others via neural structures homologous to those involved in human empathy.
Offer a treat to the rat while holding it to encourage positivity. Keep your hands open so the pet rat can move around. Gradually decrease the treats from every day to every other day to once or twice a week; this encourages the rat to trust you more, but do not completely cut off the treats.

A shriek or scream indicates strong distress or pain, such as when its tail is pinched. ▶ Occasionally, rats may hiss. Hissing is usually a sign of distress and is given at times of stress.
Anxiety and fear produce similar behavioral responses, including increased vigilance, freezing and/or hypoactivity, elevated heart rate, and suppressed food consumption.
Bartal, along with teams at UC Berkeley and the University of Chicago, has shown that the free rat may feel their trapped fellow's distress and learn to open the door. This empathic pull is so strong that rats will rescue their roommates instead of feasting on piles of chocolate chips.
Pet rats enjoy being stroked by their owners and sometimes even enjoy a gentle massage, a scratch behind the ears, or a simple tickle. Rats have also been known to return the affection by "grooming" their owners.
Mice and rats are so smart that they can recognize their names and respond when called.
You should spend at least an hour a day handling your rats if they enjoy it and letting them exercise outside their cage, so it's important to know how to pick them up.
To be happy and well-adjusted, your rats will need at least an hour of playtime outside their cage every day for exercise and stimulation, preferably in the evenings when they tend to be most active.
