Lymphocytes are a type of white blood cell. There are two types of lymphocytes of the acquired immune system: T cells and B cells. There is a third type of lymphocyte known as natural killer (NK) cells, but these are a part of the innate immune system.
A Very Brief History. The original Bengal cats are a hybrid of the Asian Leopard Cat and domestic cats. They were developed by various people, most notably Jean Sugden Mill, in the 1970s and 80s with the aim of harnessing the beauty of the wild cat, yet maintaining the temperament of the domestic cat.
Some breeds are more aggressive than others. Bengal cats - a cross-breed of domestic cats and Asian leopard cats - have a reputation for attacking cats in neighbouring houses, says Bradshaw. By contrast, he says, Persians and Siamese cats have typically forgotten how to be good hunters.
