Experienced and professional animal trainer provide their insights in answering this question :
A. You need to have this looked at by a vet right away. The tail could be broken and is likely very painful. It could also become infected and the licking will only worsen the infection. If the infection reaches the blood stream, then your rat will become septic and that is a very dangerous situation. Please seek veterinary attention as soon as possible.

How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

If your rat is living in drafty area, and the conditions cannot be changed by moving the cage, you will need to regularly check your rat`s feet and tail for any changes in skin color. The normal skin color for a rat is a healthy pink. In ringtail syndrome the skin will turn to an unhealthy blue or grey color.
If your rat is experiencing respiratory distress (e.g. gasping or labored breathing), and/or their gums, ears, feet, or tail appear to be blue-tinge (cyanotic) or is turning pale, oxygen therapy should be initiated. Consult your vet.
How should I handle my rats? Rats can be lifted by their tails but great caution must be exercised in doing so. The skin of a rat`s tail can easily tear, so it is best to grasp only the base of the tail. Furthermore, suspending the entire weight a rat by its tail is, no doubt, painful for the rat.
If the tail is extremely dirty and crusted in grime, or if it is looking drier and scalier than usual, then a deep clean might be necessary. Unfortunately, this usually requires some soaking to help loosen the gunk, which most rats are none-too-pleased about.
Ringtail, also known as tail necrosis, is an epidermal disease that may occur in rats, mice, hamsters and other rodents.
Low humidity, high temperatures, and drafts predispose young rats to develop a ring-like constriction of the tail called ringtail. This condition can also involve the feet or toes. Ringtail is most often seen in laboratory rats and is fairly rare in rats kept as pets.
A form of congenital hypotrichosis, commonly know as the “rat-tail syndrome,” occurs in a small percentage of calves produced by crossing some Continental cattle breeds with cattle that are black in color.
Do not kiss, nuzzle, or hold rats close to your face. This can startle your rats and also increase your chances of being bitten. Bites can spread germs and can make you sick. You don`t have to touch pet rats to get sick from their germs.
Positive Signs

Well rounded tail – this is where the cross section of the tail is round or oval, there are no clear corners or edges to it and it looks and feels full. Good tail “feel” – the tail feels smooth when stroked down towards the tip, there isn`t any sign of dryness or lumpiness, all scales are even and flat.

Rats can cry tears just like humans, and, like humans, they do so when they are sad, upset, stressed, or sick.
Rats are social creatures and need the company of other rats. They use their sense of smell to recognise others, finding out about where they`ve been and what they`ve been doing. As rats are social animals, they can get depressed and develop abnormal behaviour if they live on their own.
Fact #2: Rats love to be petted in certain spots.

Your rat probably likes having the top of his head stroked and gently scratched. He also appreciates it if you pet him along his back, from his neck to about the middle — the area closest to the tail can be sensitive.

The rat`s tail consists of a core layer of bone surrounded by tendons and covered by skin. Many arteries and veins run through the tail between the tendons. These blood vessels make the rat`s tail very sensitive to its environment and aid in temperature regulation.
What Does Tail Rot Look Like on a Bearded Dragon. Tail rot primarily affects the tail, but can also affect toes of bearded dragons. The tail, or toes, will gradually begin turning black and become dry and brittle due to lack of blood flow. There may also be no sensation left in the tail.
Wet-tail or proliferative ileitis, is a disease in rodents kept in cages, mainly hamsters, but can include rabbits, gerbils, rats, and mice.
Rats Can Live Without Their Tails

Speaking of tails, rats actually do not need them to survive and cannot regenerate a new one if they lose the tail. This is interesting, considering the tail is part of their vertebral column and is therefore a crucial part of their physical make-up.

Sudden death (within 48 hours of initial signs) in young animals or those stressed by overcrowding, poor hygiene, extreme environmental temperatures, parasitic infections or malnutrition. Another form of the disease results in chronic wasting and death. Diarrhoea may or may not be noted.
Treatment. Your rat`s fight wounds can be treated by cleaning them with a disinfectant solution, draining the abscesses, and applying appropriate antibiotic ointments. Your veterinarian will go over the appropriate treatments, medications, and methods for treatment so that you can care for your rats at home.
Rats and mice are known to carry many diseases. These diseases can spread to people directly, through handling of rodents; contact with rodent feces (poop), urine, or saliva (such as through breathing in air or eating food that is contaminated with rodent waste); or rodent bites.
When rats don`t like something, they tell us in their behavior. They pull away, or flinch, or even push us away. These rats stay in place, quiet, and are very relaxed. I would call tail-flicking an expression of enjoyment in this context.
Many times, this condition occurs when they are wagging their tail, which is why it`s coined happy tail syndrome. This condition is anything but happy for dogs and pet parents. The tip of the dog`s tail becomes dried and cracked and starts bleeding because of the repetitive striking of the tail on surfaces.
Nibbling On You

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.

Rats have excellent memories. 3. 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.
While rats do enjoy human interaction, they`ll need to be picked up and handled from a young age so they`re used to it. Rats rarely bite and their larger size makes them easier to pick up. This means they`re a really good choice of pet for children of all ages.

the most relevant questions and answers related to your specific issue

Q. How should I interpret my cat’s tail movements?
ANSWER : A. Our feline friends express themselves in many different ways, including through the use of their tails. Most pet owners pay close attention to a happy or excited dog, but they are sometimes less attentive to the posture and movement of their cat. Here are some of the most common cat tail behaviors, and the underlying emotion behind each action:

A flicking tail: Many anxious, nervous or stressed cats will hold their tail in a low position and flick it quickly back and forth. This is often referred to as angry tail, and a pet owner or veterinarian should be on guard for any possible aggressive or defensive activity. If a cat is moving their tail slowly, and not exhibiting the flicking motion, then this cat is at a much calmer state.

Vertical position: Most of the time when a cat is holding their tail in a straight, vertical position this is indicating curiosity and a playful mood. A cat chasing after a laser pointer or playing toys will often have their tails in a vertical position showing their enjoyment. This position also helps with balanced movements. In contrast, if the tail is in the vertical position and the cat’s back is arched with pinned back ears then this could demonstrate a feeling of being threatened and thus result in defensive or aggressive behaviors.

The Tucked Tail: Similar to a dog, a tucked tail often indicates submission or fear. Your cat is conveying upset feelings and should most likely be left alone. This tucked tail appearance can also make a cat look smaller and less threatening to an aggressive cat.

The Tail Twine: Cats will often hook their tail around another cat’s tail, owner’s legs or other objects to show a friendly and affectionate nature. They are also trying to indicate whether they want to receive affection from their owners, be fed or have playtime.

The next time you are home with your feline companion take note on how they express themselves through their tail movements, their ears, body posture and vocalization. You can start to better understand their needs and wants, in addition to what makes them uncomfortable or happy. Cats will surprise you with their array of emotions and varied expressions they can express.

Q. My cat is excessively scrstching herself., to the point she has sores. She is strictly an indoor cat. Did have flees been treated for 2 months
ANSWER : A. For every flea you see on your pet, there are 100 more in the environment. Get your pet on a good topical or oral flea control through your vet. In flea control, you get what you pay for. Consider asking your vet for a dose of Capstar. It helps get the problem under control by killing the fleas on the pet starting in five minutes but only lasts for 24 hours.

You need to treat your home environment. If you use a pest control service, tell them you are having a flea problem and they can adjust their treatment. Use a premise spray that also contains an IGR, insect growth regulator. This keeps eggs and larvae from maturing into adults and helps break the life cycle. Also, vacuum EVERY DAY, throwing out the bag or emptying the canister every time into an outside receptacle and spraying the contents with insecticide to kill the fleas you’ve vacuumed up.

Treat your yard too, since fleas are opportunistic and will hop a ride into your home on your pant leg without you knowing it. Concentrate on areas under bushes, in the shade. Fleas are less likely to be located in open sunny areas where it gets hot.

If chemicals are a problem, you can use borax. Sprinkle it into rugs, into corners and under furniture, use a broom to work it into the fibers and let it sit for hours, days even. It won’t hurt you or your pet to have it present. Then vacuum it up, reapply as needed. Food grade diatomaceous earth can be gotten from a health food store and worked into the rugs and corners in the same way as borax. These treatments aren’t as fast and effective as chemical insecticides but they can help.

You might want to consider boarding your pet for the day at your vet, to give you the opportunity to flea bomb your house without having to worry about your pet being exposed. They can bathe your pet and give a dose of Capstar while you treat your home.

Be patient, you may have to repeat these steps multiple times 10-14 days apart to help break the flea life cycle.

Skin problems can have a variety of causes, sometimes more than one. It is important to have the problem checked by your vet to determine if there is a medical cause for your pet’s skin issues and treat accordingly.

In pets of all ages, fleas, food allergies and exposure to chemical irritants such as cleaners and soaps can be a cause. Any one of these may not be enough to trigger the breakouts, depending on how sensitive your pet is, but a combination can be enough to start the itch-scratch cycle. Finding out the cause and eliminating it is the best course of action. With flea allergies, if your pet is sensitive enough, a single bite can cause them to break out scratch enough to tear their skin.

Check for fleas with a flea comb. Look for fleas and/or tiny black granules, like coarse black pepper. This is flea feces, consisting of digested, dried blood. You may find tiny white particles, like salt, which are the flea eggs. Applying a good topical monthly flea treatment and aggressively treating your house and yard will help break the flea life cycle.

If you use plastic bowls, this is a possible cause for hair loss, though this tends to be on the chin, where their skin touches the bowl while they eat. If you suspect this to be the culprit, try changing the bowls to glass, metal or ceramic.

Food allergies are often caused by sensitivity to a protein in the food. Hill’s Science Diet offers some non-prescription options for sensitive skin as well as prescription hypoallergenic foods for more severe cases. Royal Canin carries limited protein diets that may also offer some relief. Your vet can recommend a specific diet that will help.

If there is no relief or not enough, consider getting your pet checked by a veterinary dermatologist and having allergy testing done.

Q. How do I determine how much my overweight pet should weigh?
ANSWER : A. There are many tools to determine overweight and obesity levels in pets. A new tool, morphometric measurements and body fat index, are available to accurately determine a pet’s ideal weight; this will allow an accurate determination of the amount of food a pet should receive to achieve weight loss. Feeding the correct amount will lead to greater weight loss success.

There are many weight loss food options to help pets reach their ideal weight. Your veterinarian can help make a ideal weight recommendation. Here are some tips to help your dog lose weight in a healthy and safe way:

1. Diet: Providing a healthy and well balanced diet is essential to your pet’s overall health. Finding the right food for your dog can be a challenging process. For those overweight animals many commercial dog companies offer weight loss diets, but it is important to evaluate food labels for adequate nutritional content.

You want to ensure you are not missing other essential vitamin or mineral content. Volume of food is also important and the amount of food that works for one breed of dog may not be the same for another breed of dog. Portion control as opposed to free-choice feeding can help your dog to drop a few unnecessary pounds.

There are also prescription weight loss foods designed by veterinary nutritionists, such as Hill’s r/d (http://bit.ly/1AoENSd). Some pet owners find that home cooking is the best option for helping to provide a well-balanced and realistic diet plan. There are websites such as balanceit.com that offers recipes to fit your dog’s specific needs. Consulting with your veterinarian or a veterinary nutritionist to find the appropriate diet is a great way to help your dog be as healthy as possible.

2. Exercise: Another great tactic for weight loss for your dog is exercise. Whether this is through running, walking or playing with a favorite toy all of these are wonderful types of exercise to help keep your dog at a lean and healthy weight.

For those pet owners with busy schedules utilizing professional dog walking services or playtime through dog daycare services is another option. It has been shown that those pet owners that exercise regularly with their pets generally live a healthier lifestyle.

3. Physical therapy: As animals age pet owners offer encounter their favorite canine having more difficulty walking and have a dwindling desire to play with toys. Physical therapy, specifically hydrotherapy is a wonderful way to help older and arthritic animals gain more mobility and lose weight. Hydrotherapy has been proven to have several therapeutic effects on the body including, muscle strengthening, relief of swelling, decreased joint pain, less stiffness in limbs, improved circulation, weight loss, and increased tissue healing to name a few.

4. Veterinary visit and blood work: Weight gain can also be related to underlying health concerns such as hypothyroidism or other endocrine disorders. Scheduling a veterinary evaluation and routine blood work can be another important component in increasing the longevity of your dog’s life. Conditions such as hypothyroidism that predispose dogs to gain weight can be treated with a daily medication to improve hormonal balance. If feel that your dog is unnecessarily overweight there can be an underlying health condition that needs to be addressed.

5. Healthy treats: Pet owners love the chance to reward their favorite canine companion with treats and most dogs jump at the chance to consume these delicious products. The problem is many treats, which can include commercial dog treats or table scrapes can add many unnecessary calories to your dog’s daily intake. Reading labels and making note of the calories in these treats is an important component of understanding your dog’s overall health. Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation. A pet owner can add steamed or pureed vegetables, such as carrots, green beans or sweet potato to add more fiber and thus a fuller feeling for your dog.

Q. Why does my dog want to always lick our lips when she gets in our face. More aggressive when we come home the licking is very aggressive. need to stop
ANSWER : A. This is an unwanted behavior that you will have to do some training with your pet to get it to stop. Some pets just like to lick to show affection. I would recommend working with an animal behaviorist or animal trainer to help curb the unwanted behavior. You have to work with someone either one or one, or purchase a dog training book that goes through step by step how to stop this. It is more than can be covered in a brief reply box here on the site. If she is jumping up on your before licking, then you have to first address the unwanted jumping behavior.

Another tid bit is to make sure that when your pet does not jump or lick that you provide positive rewards for good behavior as well. And to remain cool and calm because our pets are more receptive when we have a good attitude during their training. Good luck!

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.
