A. For its best chance of survival you need to take it to your local wildlife rescue. They will have appropriate medications and know exactly what to feed it. You have to remember it is a wild animal so being in captivity especially in a house with other pets that it sees as predators and unusual noises will be extremely stressful for it which can delay healing at best or put it into fatal shock at worst.

How to Identify Common Pet Problems ?

For an injured shrew, as for any other animal, the way to help it is to get it to a rehabilitation person or to a vet as quickly as possible.
Any injured animal may be overcome by shock. Cover the animal with a blanket to preserve body heat and be sure the animal can breathe, and transport the animal to a veterinarian immediately. Signs include: excessive bleeding, cuts, abrasions, and gashes. Open wounds and bleeding must be attended to immediately.
Unlike other mammals, some species of shrews have toxic saliva used for hunting. This shrew venom gets into wounds as the animals bite, paralyzing the prey. As a result, shrews are venomous, not poisonous.
The common shrew is always hungry: it needs to eat 80-90% of its body weight every day to survive. It mainly preys on insects, but will also eat slugs and snails, and will happily tackle earthworms as long as 10cm – bigger than its own body!
Common Diseases Shrews Carry

Long-term problems include nerve pain, arthritis, and short-term memory loss. Rat fleas are also found on shrews and carry the bacteria that causes bubonic plague. If left untreated, this disease spreads through the body and can be fatal.

The saliva of these little beasts packs a potent punch to its prey in the form of a neurotoxin. Short-tailed shrews can be deadly to animals as large as frogs and small rodents, but they are not dangerous to humans or domestic animals. Short-tailed shrews still can deliver a sharp bite if handled, though!
It`s no secret that dogs have an enhanced sense of smell, granting them the ability to sniff out and detect various items, from firearms to narcotics. It`s less well known, however, that dogs also have the ability to detect injuries that even medical professionals did not know about.
General wound care begins after the animal has been stabilized if it has undergone a trauma or is in shock. First aid, such as pressure to stop bleeding and basic bandaging, is generally done quickly. Irrigation of the wound, called lavage, washes away both visible and microscopic debris.
Social Interaction: When they`re not breeding, shrews are solitary animals that live and forage alone. They`re extremely territorial and aggressive against other shrews, animals and even people.
Some shrew breeds carry a poison in their saliva. Most cats do not eat shrews because they smell and taste bad. The cats that do eat shrews do not seem to fall ill, however, some may feel sick. Occasionally cats get bitten by shrews.
Since shrews must eat every 2-3 hours to survive they are often seen at the surface foraging for food, but live in burrows which may have been used previously by another animal.
Food and predators: Shrews eat insects, spiders and other small invertebrates. Some species are dependent upon plant matter, but most will eat any kind of meat.
The virus is called Langya henipavirus or LayV, and patients reported symptoms that include fever, fatigue, cough, nausea and headaches. Some people also developed blood cell abnormalities and impaired liver and kidney functions, the report said.
The forest-dwelling masked shrew is host to many varieties of parasites and pathogens, and together they could be the world`s newest indicators of environmental change, according to a Kansas State University researcher`s study in NOAA`s 2016 Arctic Report Card.
Shrews have saliva that is poisonous but that can`t be ingested through the tissue in the mouth, meaning they are effectively immune to their own toxin.
Shrews carries a pungent smell and they are very wild in nature, its venomous bite is painful to humans and can kill small animals. A very unlikely critter to keep as pets.
Shrews are very territorial and may occasionally behave aggressively toward pets or humans. Shrews are unusual creatures. They`re very small, but they can be very aggressive.
Many wounds, such as minor abrasions, bruises, or small cuts, require little to no treatment and can heal on their own, while others may require more intensive treatment. Here`s an all-in-one guide to cat wounds, from how to identify the most likely cause to how to clean the wound and whether you need to see a vet.
Several studies have shown that the response to unwanted pain works the same way in animals. “The changes to their brain waves and physiology are very similar to what you would find in humans,” says Reyes-Illg. Despite knowing that animals feel pain, not all of their pain is treated the same way.
Mammals share the same nervous system, neurochemicals, perceptions, and emotions, all of which are integrated into the experience of pain, says Marc Bekoff, evolutionary biologist and author. Whether mammals feel pain like we do is unknown, Bekoff says—but that doesn`t mean they don`t experience it.
Yes, it`s true. Animals cry. A couple of years ago, zoologists which are people who study animals and their behavior, discovered that some animals, when they feel pain, scared or sad, also cry… like human beings.
What should I clean the wound with? Warm tap water is recommended for cleaning most wounds. Warm saline (salt solution) may also be used. This may be made by adding approximately one level teaspoonful (5 mL) of salt (or Epsom salts) to two cups (500 mL) of water.
Relative to its body mass, the hero shrew`s spine is stronger than that of any other vertebrate3. The hero shrew has even been reported, anecdotally, to be able to withstand the weight of a full-grown man on its back4.
Characteristics: Shrews are small, mole-like mammals that look a bit like long-nosed mice. They have an elongated snout with dense fur of a uniform color, usually gray to black with small eyes and five clawed toes on each foot.

the most relevant questions and answers related to your specific issue

Q. I found a hurt shrew today, it has a small gash in its side near its stomach. What can I do to care for it until and after it has recovered?
ANSWER : A. For its best chance of survival you need to take it to your local wildlife rescue. They will have appropriate medications and know exactly what to feed it. You have to remember it is a wild animal so being in captivity especially in a house with other pets that it sees as predators and unusual noises will be extremely stressful for it which can delay healing at best or put it into fatal shock at worst.

Q. Which common foods are poisonous to pets?
ANSWER : A. That’s a great question. As responsible pet owners we need to be aware of food items that can be harmful to our canine or feline companions. Here are some of the most common foods proven to cause illness in our animals at home:

Chocolate: A favorite and irresistible treat amongst most humans, chocolate is considered toxic to dogs. In very small amounts it is usually not a huge issue, but with larger volumes and with darker chocolates pet owners should be concerned. Chocolate contains methylxanthine theobromine, which is similar to caffeine. Chocolate ingestion can cause vomiting, diarrhea, hyperactivity, issues with normal heartbeats, seizures, and in some severe cases, death. It is best to keep your favorite chocolate treats in a good hiding spot and out of reach of your dog or cat.

Grapes and raisins: Dogs should not consume grapes and raisins because of the risk of acute kidney failure. Most dogs experiencing grape or raisin toxicity will begin to have vomiting and/or diarrhea within 6-12 hours of ingestion. Other abnormal clinical signs include lethargy, abdominal pain, dehydration, and tremors. Kidney failure develops within 24-72 hours of the initial ingestion. There are some dogs that do not experience these devastating side effects. It is best to contact your veterinarian or veterinary emergency facility if you believe your pet has ingested grapes or raisins.

Garlic and onions: We often forget that our meals contain these two popular ingredients and will allow our furry companions a few bites or licks. Onion and garlic both can cause a type of poisoning that results in damage to red blood cells, making them more likely to rupture. They can also cause stomach upset and mouth irritation. Look for pale gums, increased breathing or drooling or any vomiting or diarrhea.

Bread dough: Unbaked bread dough is considered poisonous to our pets. The bread dough, when ingested, expands in the stomach because of the warm and moist environment. This can lead to a bloated or even twisted stomach. In addition yeast is often added to our baking products to help get bread to rise, and when this yeast is fermented it produces both carbon dioxide and alcohol. The alcohol produced can be absorbed into the bloodstream and causes dangerous drops in blood sugar, blood pressure and body temperature. Common clinical signs include vomiting or retching, distension of the stomach, weakness and collapse.

Macadamia nuts: Ingestion of these nuts are not proven to be fatal in dogs but can cause them to experience uncomfortable clinical sings, including fever, joint stiffness, vomiting, tremors and difficulty walking, especially in their hind legs. Often your pet will start to feel better after about 48 hours, but supportive veterinary care (such as pain medication) may help ease their discomfort.

Xylitol: The most common ingredient used in sugar-free gum is xylitol, which is a non-caloric sweetener. It is also found in some oral rinses, toothpastes and vitamins. Xylitol and dogs do not mix – it can cause a dangerous drop in blood sugars levels. Dogs will often display signs of disorientation, black tarry stool, tremors and seizures. If severe enough some dogs have developed liver failure. Keep your gum away from your canine companion.

Avocados: Avocados are not actually poisonous to dogs or cats but as many veterinarians can tell you the avocado pits can cause a foreign body obstruction. Avocados contain persin, which is actually toxic to the majority of pet birds. The abnormal clinical signs associated with avocado ingestion in birds include, respiratory distress, inability to perch, liver and kidney failure and sudden death.

Go forth and enjoy your favorite foods, but keep in mind which foods you should avoid sharing with your furry family members. Whenever in doubt, contact your veterinarian for healthy and safe food suggestions.

Q. I found a hurt shrew to day, it has a gash on its side near its stomach. Can I wrap a bandage around it to stop the bleeding?
ANSWER : A. I wouldn’t recommend wrapping a bandage around it as firstly you may get bitten but also it could cause internal trauma as it will need to be tight to stop bleeding which will cause internal damage. You are best to take it to your local vet or wildlife centre as they can give appropriate treatment and pain relief and medications. It’s best chance is by getting professional treatment.

Q. I have a kitten (about 3 months old) who’s ear is red and squishy sounding today (just started today) I can’t afford to go to a vet, what can I do?
ANSWER : A. If you are in financial difficulty, there are ways of still getting your pet treated by a veterinarian. Ask if they take Care Credit and apply online. This is a credit card specifically for medical, dental, and veterinary expenses.

Call a local animal shelter and ask if they have a low-cost pet clinic that works with people with limited incomes or call a college of veterinary medicine in your area and ask about a low- or no-cost veterinary care program.
