Rat First Aid

by Debbie "The Rat Lady" Ducommun

First aid is care given in an emergency. Sometimes, first aid is not enough, and your rat will also require veterinary care. If you must rush your rat to the vet, be sure to call first to let them know you’re coming. That way they’ll be prepared to help as soon as you arrive.

Respiratory Distress

A rat can experience respiratory distress without any warning, whether or not she has had previous respiratory symptoms. The signs of respiratory distress are gasping through the mouth, or dashing about in a panic. The rat may or may not have blue extremities. Respiratory distress is extremely unpleasant—one of the most distressing experiences there is—and must be treated immediately.

One of the first things to try is to get the rat to breathe air moistened by a humidifier or a shower running in the bathroom. You can also boil water on the stove, but do not let the rat inhale the steam directly, as that can burn the lungs. Hold the rat at least 3' away from the steam.

If it seems like the rat might have mucus in the throat that is blocking the free passage of air, see choking (below).

If the rat is still having trouble breathing, and the problem is constricted breathing passages (like asthma) a bronchodilator will help. The best treatment is a subcutaneous (subQ) injection of aminophylline, which will expand the breathing passages. In most cases, this will stop the respiratory distress within a matter of minutes. It is also recommended that the rat be given a subQ injection of dexamethasone to reduce inflammation in the lungs. If dexamethasone isn’t available, you can give ibuprofen at 60 mg/lb twice a day.

If aminophylline isn’t available, you can try an asthma inhaler. You can buy one called Primatene Mist at a drug store without a prescription. Put the rat in a small paper bag, inside a large plastic container or under a blanket and put two or three puffs of the medication in with the rat. Try to keep the rat there for several minutes to make sure she inhales the medicine.

If a bronchodialator doesn’t help within 15 minutes, you can try an injection of furosemide, a diuretic that will quickly flush excess fluid out of the lungs.

If none of these treatments work, the rat must be put in oxygen. If the rat doesn’t improve on oxygen it means her lungs are no longer able to work and she should be euthanized. If the rat does improve on oxygen, then you have some time to wait for other medications to work.

Once you get the rat out of respiratory distress, she should be put on both amoxicillin and Baytril. She may need continued treatment twice a day with aminophylline, an anti-inflammatory (either prednisone or an NSAID), furosemide, and perhaps even enalapril and atenolol.

Choking

Because of the arrangement of the rat’s throat, true choking is rare. If your rat appears to be choking the most likely cause is a piece of food or other substance stuck in her throat. This can cause gagging and drooling. A rat who is gagging will open her mouth wide and pull her ears back.

As long as the rat can breathe, don’t do anything accept try to comfort her. Anything you try to do to stop the gagging may make the situation worse. The offending food will eventually pass down in most cases. You might try offering your rat a small piece of bread to see if that will help push the food down, but do not use doughy bread which might make things worse.

If your rat is having real trouble breathing, and not just labored breathing, you can try doing the Heimlich maneuver, by pressing sharply up and in underneath your rat’s ribcage.

Or you can do a procedure called “the fling” which uses centrifugal force. Hold your rat firmly around the neck with one hand, and by the base of the tail with the other to hold her securely. Make sure there are no objects within an arm’s length. Lift the rat overhead and bring her down in a rapid arc, so that at the end of the path she’s tail up and head down. This can be repeated 3-4 times, then give the rat a rest, check her breathing, and see if anything is visible in the mouth. This is extremely effective in dislodging objects or mucus in the throat.

If neither of these techniques helps, you can put your mouth over the rat’s mouth and try sucking the obstruction out. Be sure you do not cover the rat’s nose. If the rat is still having trouble breathing, try a shot of dexamethasone.

If choking or gagging persists for more than 6 hours, take your rat to the vet. There may be an object lodged in the throat too big to pass down, or there might be a tumor or some other problem. Sometimes respiratory disease can cause gagging and choking due to swelling of the airway and/or too much mucus.

If your rat gags frequently, she may have mega-esophagus, a problem where the nerves to the esophagus are defective. In this case the rat must be put on a liquid diet. Offer free choice of Ensure adult nutritional drink or a similar product. Also give the rat a liquid vitamin B supplement to supply 1 mcg of B12 daily. Be sure keep all paper away from the rat as eating paper can cause a fatal blockage.

Lethargy

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. Try to get him to drink some juice, a sports drink, or sugar water with a pinch of salt. If your rat is dehydrated, try to get him to drink 1-2 ounces. If he refuses to drink, warmed saline solution for injections must be given under the skin.

If the sugary drink does not cause your rat to improve within 1-3 hours, refer to page 22 in the 9^th edition Rat Health Care booklet for treatment. (First treatment is with amoxicillin and if the rat is severely lethargic, also Baytril.)

One cause of lethargy is pesticide poisoning. This will also cause the pupils to be constricted so they do not expand in the dark. In this case you’ll need to rush your rat to the vet for an injection of atropine.

Poison Hotline

If you suspect poisoning in your rat (or other pet), here are the phone numbers for the National Animal Poison Control Center at the College of Veterinary Medicine at the University of Illinois at Urbana-Champaign.

1-900-680-0000 You will be charged $45 per case.

1-800-548-2423 You must have a credit card to use this number and you’ll be charged $45 per case. Both of these numbers are active 24 hours a day. Be ready to provide:

1. your name, address and phone number;

2. the species, breed, age, sex, weight and number of animals involved;

3. the poison, and if known, details such as amount of poison ingested, time since exposure, etc.

4. the problems your animal is experiencing.

Here is the phone number for the ASPCA Poison Control Center: 888-4ANI-HELP. You will be charged $45.

Wounds & Bleeding

The body skin of rats contains few pain receptors, and minor wounds usually bleed little and heal quickly. Rats heal so quickly wounds less than 1 ½" long do not need to be stitched. Just apply a topical antibiotic to prevent infection. I recommend using an antibiotic ointment which contains a topical anesthetic, such as Neosporin Plus. (This is also helpful for treating scratches rats sometime inflict on humans!) A rat with an open wound must be kept in a spotless cage with only rags or shredded paper because litter may contaminate the wound.

Wounds to Extremities

The feet, ears, tail and mouth all have a considerable blood supply, and injuries to these areas can cause profuse bleeding. The first step to stop the bleeding is to apply direct pressure for two minutes. If the bleeding continues, put some flour in a small container and press the bleeding area into the flour, or press some flour onto the wound. The flour will help the blood to clot. Cornstarch can also be used, as well as a commercial product to stop bleeding. Another thing to try is holding ice against the injury. The cold will reduce the blood flow.

If the injury is a severed toe or tail tip, you may have to apply a tourniquet. Tie string as close to the end of the extremity as possible. Tighten the tourniquet until the bleeding slows to an ooze. Do not tighten the tourniquet too much, or you could cause additional damage. Remove the tourniquet after 20 minutes to see if the bleeding has stopped, or can now be stopped using the other methods. If not, replace the tourniquet and take your rat to the vet.

If a toenail is bleeding, the best way to stop it is to use styptic powder or a silver nitrate stick. Flour or cornstarch can also be used like styptic powder. Press some into the end of the nail.

After a wound to a toe, it’s common for the toe to swell quite a bit and turn red. It’s not usually necessary to treat this condition and after a week or two, the toe will heal. If you like, you can give the rat an anti-inflammatory such as ibuprofen to help bring down the swelling.

If a rat is picked up by the tip of her tail, the skin will often be pulled off. The bare end of the tail will usually dry up and fall off on its own. Apply antibiotic ointment with an anesthetic, such as Neosporin Plus. Observe the tail for any sign of infection, such as pus or a bad smell and if this occurs, consult your veterinarian. Sometimes a rat will chew at the tail. If this happens, try treatment with an analgesic. You can give ibuprofen at a dose of 60 mg/lb twice a day. If that doesn’t help, you’ll have to have your vet perform an amputation.

Ibuprofen interferes with blood clotting, so if your rat has had bleeding, you do not want to use ibuprofen that day. For pain you can use acetaminophen (Tylenol) at 90-140 mg/lb every 4-12 hours. Choose the dose according to the severity of the pain and possible length of use, with lower doses for repeated use. Overdoses can damage the liver.

Bleeding from Nose, Ear or Mouth

Bleeding from inside the nose or ear is most commonly caused by an infection, which can erode away the tissue, opening a blood vessel. The size and number of the vessels determines the amount of bleeding. Nasal infections are difficult to treat and require aggressive antibiotic therapy. For bleeding from the nose, you can try holding ice to the bridge of the nose. You can also give your rat ice cream or a popsicle to eat, and hopefully the cold will penetrate the nose and help.

Bleeding from inside the mouth can also be difficult to deal with since it’s so hard to see where the blood may be coming from. It’s possible for a rat to accidently bite his tongue, and bleeding can also occur from a mouth tumor or from an injury to or tumor in the throat. Giving your rat ice cream or a popsicle may help stop the bleeding.

For bleeding from an ear, try putting pressure and/or ice against the base of the ear. Infection or cancer are the most common causes of bleeding from inside the ear, but occasionally a rat will accidently puncture his eardrum while cleaning his ear with his toenails.

If you cannot stop the bleeding after trying all these methods, you will need to take your rat to the vet where he can anesthetized for more effective procedures, such as suturing. There is also a product called Gel Foam which is a protein that becomes very sticky on contact with blood which may be able to stop bleeding from an injury. Your vet can also give a rat an injection of vitamin K to help blood clotting.

Accidents & Injuries

Accidents such as a rat getting stepped on, or falling from a height are pretty common. I’ve witnessed young rats who have experienced loss of consciousness or convulsions after a fall, and then appeared to recover completely within a few minutes. However, one of these babies started having seizures at one year of age, so immediate treatment with an anti-inflammatory such as dexamethasone after such a fall is recommended. I also know of rats who have broken their neck, nose, or leg from a fall, so you should observe your rat carefully after an accident. Being stepped on is especially dangerous since it can cause internal bleeding. If your rat appears lethargic or in pain, you should rush her to your vet. If injuries are apparent, the rat should receive an injection of dexamethasone to reduce swelling and a pain medication, or ibuprofen (see below) for swelling and pain.

Leg Injuries

Another common accident is a rat getting her leg caught in the wire of the cage. (1" X ½" mesh floors should be covered or removed to prevent this.) If you witness an injury such as this, the best immediate treatment is a cold compress to help prevent swelling. If swelling persists after 24 hours, or if the foot is swollen half again normal size or more, you need to . take your rat to the vet for an injection of dexamethasone which will quickly reduce the swelling, or treat the rat with ibuprofen at a dose of 60 mg/lb twice a day. You can use children's liquid (the berry flavor seems to be popular with rats) or you can grind up a tablet and mix it in a soft tasty food. When using the liquid ibuprofen, I recommend giving the rat a tasty treat afterwards to mask any bitter aftertaste that will cause the rat to refuse future doses.

I also had a rat who developed pain in his ankles from being on a wire floor without actually getting his legs caught. He demonstrated pain by holding one foot up or limping on it. When I moved him to a cage without wire floors, the pain went away.

Most broken legs can heal on their own, even breaks near the ankle joint that are floppy. You do not need to keep the rat isolated or quiet. Treat the pain and swelling with ibuprofen at a dose of 60 mg/lb twice a day. For a compound fracture, where the bone breaks the skin, you must take your rat to a vet as the leg may need to be pinned or amputated.

Swelling

Sudden severe swelling, especially on the face, can occur from an injury or from an insect or spider bite. You can treat swelling with ibuprofen (see above). Or you can take your rat to the vet for a shot of dexamethasone. (Swellings can also be abscesses, which can appear fairly suddenly.)

An injury to the flap of the ear can result in a hematoma. This is a pocket of blood that forms under the skin. DO NOT try to lance a hematoma because this can cause profuse bleeding that is difficult to stop. A hematoma of the ear will eventually resolve on its own, although this may disfigure the ear. It this bothers you, you can have your vet repair the hematoma surgically.

Heat Stroke

Because rats are so small, and not well adapted to heat, they can succumb to heat stroke quickly. Situations that can cause heat stroke include leaving your rat in the sun or outside in warm weather, too close to a heater, or on a heating pad. The symptoms of heat stroke can include drooling and lethargy or unconsciousness. The tail will be quite warm to the touch. You must quickly cool the rat by submerging her up to her neck in lukewarm water. Also encourage her to drink an electrolyte beverage or water containing some sugar and salt. If she doesn’t recover quickly, rush her to your vet.

Shock & CPR

There are two types of shock we need to be concerned about: electrical shock and physiological shock. Electrical shock can occur when a rat chews through a power cord. Electrocution can cause unconsciousness and can also stop breathing. In this case, you must do mouth-to-nose respiration to start the breathing again.

Place your lips around the rat’s nose and blow into her lungs. You will have to blow fairly hard, enough to make the chest expand, but not too hard. After blowing 2-3 times, check to see if breathing has started. If not, firmly massage the chest for a couple of seconds and then blow in their nose again. Alternate the chest massage with blowing into the lungs. Firmly slapping the body can also stimulate breathing. Do not give up too easily. You may have to work for several minutes to restore the breathing.

Electrocution can also cause burns, especially to the mouth. Burns are not always obvious on animals with fur so if your rat has been electrocuted, a veterinary exam is good precaution.

Physiological shock is a condition where the circulation system shuts down because of blood loss, extreme stress, or other failure of normal body systems, and is an extreme emergency. The symptoms include extreme lethargy, dull eyes, and low body temperature. Keep your rat warm and her head lower than her body while rushing her to the vet for an injection of dexamethasone and possible fluid therapy.
