Aversive stimulus

An unpleasant or painful stimulus.


A Bilateral is a cat that has both a right and left side. This means this cat has two eyes, two ears, two legs, two tails, and two noses. Bilateral cats are usually born this way but can also be born with only one eye or ear.


A biopsy is a medical procedure that removes a tissue sample from a part of the body. It is used to diagnose a disease or to find cancer cells. A biopsy is performed when the doctor suspects something is wrong with the tissue. A biopsy may determine whether there is cancer or a benign growth (such as a cyst).

Breech birth

Breech birth is a type of birth that occurs when the baby comes out feet first. This is different from a Cephalic Birth when the baby comes out head first.

Corticosteroids are a class of drugs used to treat various conditions, including inflammatory conditions, autoimmune diseases, allergies, and asthma. They can also be used to prevent the rejection of transplanted organs. Corticosteroids are often given to cats with severe allergies, asthma, cancer, kidney disease, or liver disease to reduce swelling. These drugs may also be given to cats who are having surgery.

There are two types of diabetes:

Diabetes insipidus

Diabetes Mellitus

Diabetes mellitus is a condition that occurs when your body does not produce enough insulin, or your cells do not respond to the insulin that is produced. Cats with diabetes mellitus usually have either type 1 or 2 diabetes mellitus. Type 1 diabetes mellitus is when the pancreas does not produce insulin. This means that your body does not produce any insulin at all. Type 2 diabetes mellitus is when the pancreas produces insulin, but the cells in your body do not respond to the insulin produced.

Dyspnoea is a condition that causes breathing difficulties. It is not uncommon for cats to experience this condition due to several factors, including poor air quality, infections, and respiratory illnesses. Cats that are underweight or have a respiratory illness, such as Feline Lower Respiratory Disease (FLRD), may be at higher risk of developing dyspnoea.


An embolus is a word created by veterinarians to describe a medical condition in cats that causes them to stop eating and drinking. It is not a disease but rather a condition that requires treatment. The cause of the condition is usually unknown. However, some common causes can lead to this condition, including kidney, liver, and heart problems. The condition is typically treated by using fluids to rehydrate the cat.

Endoparasites are parasites that live within the body of their host. They may cause disease or discomfort in their hosts. Cats are often carriers of endoparasites. The most common types of endoparasites found in cats are roundworms, hookworms, whipworms, tapeworms, fleas, ticks, and mites. These parasites can cause various cat problems, including skin irritation, diarrhea, weight loss, anemia, hair loss, and other health issues.

Feline Immunodeficiency Virus (FIV)

Feline Immunodeficiency Virus (FIV) is a virus that causes a disease in cats called Feline AIDS. Its most common form is FIV-1, which is a retrovirus. Cats infected with FIV can pass the virus to other cats through bite wounds and saliva.

Feline Leukemia Virus (FelV)

Feline leukemia virus is a virus that causes a disease called feline leukemia in cats. It is fatal in some cases. The symptoms of the disease include loss of appetite, vomiting, diarrhea, weight loss, and blood in the urine or stool. It can also cause neurological problems such as paralysis.

Feline odontoclastic resorptive lesion (FORL)

The feline odontoclastic resorptive lesion is a disease caused by an infection of the oral cavity of a cat. It is characterized by the formation of resorption pits in the teeth of the cat. The condition is sometimes referred to as a feline periodontal or dental disease. This condition is often confused with gingivitis or periodontitis in humans. However, it is not contagious. The disease usually begins with gum inflammation, followed by the appearance of tartar and the tooth’s enamel resorption. The tartar and the resorption of the enamel causing the teeth to become loose and fall out. The disease may occur in the mouth, jaw, cheek, tongue, gums, lips, or face.


Gestation is a word used to describe the time between a male cat’s mating and its offspring’s birth. In many species of animals, gestation is about 40 days, while in felines, it lasts approximately 63 days. Cats go into heat cycles to trigger ovulation, which is the release of an egg from an ovary. After the egg is released, it travels down the oviduct, fertilized by a sperm. The fertilized egg then attaches to the uterus wall, which will stay until it is ready to be born.


Granuloma is a skin condition that causes your cat’s skin to swell up. This is usually caused by a bacterial infection that travels from your cat’s nose or mouth to its skin. Your cat may also get a fever, lose weight, and have trouble breathing. Treatment includes cleaning your cat’s nose and mouth and giving it antibiotics.


Bleeding into the lungs or chest fills the air spaces.


Haemothorax is a type of trauma caused by a penetrating wound to the thorax. The lungs are the most common organ injured. Other organs that may be affected include the heart, esophagus, liver, spleen, kidney, stomach, and intestines. Cats are prone to haemothorax because of their anatomical structure. Their chest cavity is divided into two halves by a strong rib cage. This creates a space between the two lung lobes. If a cat gets hit by a sharp object, the object pierces the chest wall and enters the space between the lung lobes. The object may move into one or both lung lobes and cause bleeding.


Idiopathic means that the cause is unknown. It can apply to humans or animals. The most common cause of idiopathic disease in cats is the feline immunodeficiency virus (FIV). It is also called feline-acquired immunodeficiency syndrome (FAIDS). Other causes of the idiopathic disease include immune-mediated diseases such as lymphosarcoma and genetic disorders.


Leucopenia is a condition that occurs when there is a lack of white blood cells in the blood. This leads to anemia or low levels of red blood cells in the body. It can be caused by several conditions, including infections, immune disorders, tumors, and parasites.


Lymph is a fluid that circulates through the lymphatic system. Lymph is part of the immune system. It helps fight infections and cancer cells and remove cellular debris. The lymphatic system is a network of vessels, lymph nodes, and lymphoid tissues that drain lymph from the blood and return it to the bloodstream.

When cats ‘mark.’

Cats mark their territory by spraying urine on trees and shrubs. Cats mark their territory by rubbing their face, ears, legs, tail, and back against tree trunks or shrubs. They may also spray urine on garbage cans, fences, and walls.

What does ‘metastasis’ mean in cat cancer?

Metastasis means cancer has spread from its original location to other body parts. It is a common term used in cancer treatment.

The term metastasis usually refers to cancer that has spread from its original location to another body area. This is usually caused by the cancer cells traveling through the lymphatic system or bloodstream. Cancer that spreads to the lungs is called “pulmonary metastasis.” Cancer that spreads to the liver is called “hepatic metastasis.” Cancer that spreads to the bones is called “osteosarcoma.” The treatment for this varies depending on the type of cancer and where it has spread.

Where does a microchip go in a cat?

Microchips are implanted in cats to identify if they get lost. The chip is usually placed under the skin between the shoulder blades. There is no particular procedure to remove a microchip from a cat, but it is crucial to take your cat to a vet for regular check-ups. If your cat gets lost, your vet can find it by reading the microchip.
