It could indicate pain if your rat suddenly screeches, squeaks, whimpers, or makes any other sound that wasn't made before when touched or picked up. If this happens, gently feel your rat over thoroughly to identify the source of the pain. Pay close attention to the abdomen, legs, feet, and tail.
The best way to tell if a rat's happy, according to a new study, is to look at its ears. A happy rat's ears hang relaxed to the sides (right), instead of perked up (left). Please be respectful of copyright.
Ways Rats Show Sadness
Lethargy: When depressed, rats often become unmotivated by life; because of this they will become lethargic and sleep most of the day. Lack of appetite: Depressed or sad rats will often begin to have a decreased appetite due to their bodies releasing stress-induced hormones.
Putting your rat's favourite blanket or toy in the travel carrier will calm him. As mentioned above, a blanket will provide your rat with something to nestle into. To calm your rat further, use your rat's favourite blanket.
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.

Mice and rats have a preference for water with sucrose dissolved in it over regular water. When a rodent shows a lack of interest in the sucrose solution, it is said to be exhibiting anhedonia which is a classic attribute of depression (Klein, 1974).
When you notice your rat doing something abnormal, consider whether it could be a sign of illness or pain. Some common behaviors associated with rat health problems include a hunched posture, staring, stumbling, head tilt, failure to groom, sneezing, and wheezing.
Rats can build strong bonds with humans (and even high-five!) As well as interacting with their cage mates, pet rats can build strong bonds with their owners too.
They have an excellent sense of touch, and a wonderful sense of smell. They're normally active at night and at dawn and dusk. Rats live for around 2 years, but some may live longer.
Pet rats need to breathe through their noses, and cannot sustain breathing through their mouths. Mouth breathing is often triggered by stress or other illness, and tragically can forewarn of death. If your pet rat is breathing funny, take a look at this brief video and see what mouth breathing looks like.
Performing the Pinch Test
Grab with your thumb and forefinger and pull the animal's skin away from its body. A well-hydrated animal's skin will return to a normal position within 1 second. An animal suffering from dehydration will lack elasticity and stay in a peaked position longer.
Acetaminophen (Paracetamol)
Paracetamol can be used to alleviate mild pain in rodents and can be administered to rodents if stronger analgesics are not appropriate. This can be administered in the drinking water. Paediatric preparations are suitable (Tylenol 1-2mg/ml in drinking water).
Once again, science has shown what common sense has been telling us all along: Rats and mice, like all animals, feel pain and pleasure, and they suffer when they're used as laboratory equipment.
Lethargy in rats is a serious symptom that needs immediate attention. Give your rat a full exam to look for other signs, especially dehydration and lumps in the abdomen. Even if your rat is not dehydrated, he might have low blood sugar or an electrolyte imbalance.
Excited rats may also jump, hop, or “popcorn” when they are happy. They may run excitedly at full speed around the house or enclosure—just like how dogs get the “zoomies.”
Rats are exploratory; however, at the same time, they are naturally neophobic (the fear and avoidance of new objects). Neophobia is a survival mechanism to protect from the new and unknown and often occurs when rats are presented with freshly placed rodenticide bait or bait box or monitoring devices.
Rat health checks
Common problems include tumours (especially in females), breathing problems, obesity and overgrown teeth. Knowing how they behave normally - being familiar with them and their normal behaviour will help you bond and notice if they're unwell.
Anxiety and fear produce similar behavioral responses, including increased vigilance, freezing and/or hypoactivity, elevated heart rate, and suppressed food consumption.
Taken together, this evidence supports our conclusion that rats experience negative emotions during and after CO2 exposure, and that these emotions likely correspond to fear, anxiety, dyspnea, distress, and panic.
As NatGeo explains, the rats that regretted their decision would think about that specific flavor of food that they passed up: "'That's the regret,' says [neuroscientist David] Redish. Not only were the rats physically looking backward; they were also thinking about the choice they hadn't made."
Underwater trauma
Exposed rats demonstrated immediate and persistent (7–30 days post-stress) increased arousal in acoustic startle response (ASR) and anxiety-like behavior in the elevated-plus maze (EPM) tests compared to control rats that swam without submersion43,44,45.
Wheezing in rats sounds similar to wheezing in humans; it's a whistling noise in the breathing. While wheezing often does happen when your rat is rattling, they don't always go together. This noise is usually a symptom of a new respiratory infection, or sometimes it can be linked to a mycoplasma flare.
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.
