Cat fleas can transmit parasites, bacteria, and viruses, such as tapeworms, plague, and cat scratch disease. They can cause various health problems for their hosts, such as skin irritation, allergic reactions, anemia, and transmission of diseases like cat scratch fever and tapeworms. Cat fleas are difficult to control because they have a complex life cycle and can survive for long periods without a host.
Cat fleas are small, wingless insects that feed on blood and can jump up to 150 times their body length. They are very adaptable and can survive in a wide range of temperatures and humidities. They prefer warm and humid environments, such as those found indoors or on animals. They can also survive for long periods without feeding, especially in the pupal stage. However, they are vulnerable to desiccation, freezing, and insecticides.
