The function of white blood cells (also called leukocytes) is to defend the body against infection. There are 2 main types of white blood cells: phagocytes and lymphocytes.
The main function of red blood cells (also called erythrocytes) is to carry oxygen to the tissues. Oxygen is carried within red blood cells by molecules called hemoglobin. Oxygen is used by cells to produce energy the body needs. Carbon dioxide is left behind as a waste product during this process. The red blood cells then carry carbon dioxide away from the tissues and back
Blood cells form and develop mostly in the bone marrow, that is, the tissue located in the cavities of bones. Blood performs a variety of important functions as it circulates throughout the body. It delivers oxygen and vital nutrients (such as vitamins, minerals, fats, and sugars) to the tissues. It carries carbon dioxide to the lungs to be exhaled and waste products t
The most common feline behavior problems are associated with elimination. Some of these are related to the litter box, while others reflect social conflicts and involve anxiety or aggression. Much feline aggression is subtle and passive, so its real frequency may be greatly underestimated.
For both the prevention and treatment of behavior problem
Although many people think of cats as solitary animals, they are very sociable in the right circumstances. Some indoor cats may prefer living alone, but many get along well in groups. Outdoor cats will form stable groups as long as they can find enough food.
Unlike dogs, cats have not been artificially bred to perform specific tasks. Instead of sel
The treatment of behavior problems depends on the disorder and its outlook. In general, the program begins with prevention and avoidance of problems, while you and your veterinarian develop strategies to modify the cat’s behavior. Prevention is especially important in cases of aggression to ensure safety for owners and pets. Avoiding problematic behaviors is also important
Many “health” problems faced by pet cats are associated with behavior problems or unmet expectations about behavior. Your veterinarian will first need to rule out any possible health problems that could be causing your cat’s behavior to change. For example, a medical condition could be causing your cat to become aggressive or to urinate in the house. Stress can also hav
Behavioral medicine is the scientific study of everything animals do, whether the animals are insects, birds, mammals, fish, or people. The field of animal behavior is concerned with understanding the causes, functions, development, and evolution of behavior. Behavior refers to the actions or reactions of an organism. Behavior is usually in relation to the environment, and is
Kittens can generally be taken from their mother and littermates once they are weaned, beginning at 6 to 7 weeks of age. Kittens, like babies, require a lot of attention, including veterinary care, feeding, and socialization.
Like dogs, cats also have an estrous, or heat, cycle. However, female cats, which are called queens, are induced ovulators. This means that they do not ovulate (pass an egg) unless they are bred. This greatly increases the chances of conception when bred, which is why stray queens often have many kittens per year. The queen can enter her first heat as young as 4 m
