Cats are clean animals as they spend a large amount of time grooming themselves each day. In the majority of cases, cats lead a very happy and long life without too many problems. They don t cost very much because cat food and litter are very cheap. They don t require as many vet visits for routine shots either like dogs do which can become quite expensive. Cats associate the clicker with a good behavior they will use for a long time. Clicker training is associated with classical condition (they associate the sound with food.) and operant conditioning (cat performs movement to receive food). Why use a clicker and not tell a cat or make a sound to get your cat to do a trick? Cats usually take care of their own grooming so the owner need not worry about this aspect. Cats like to clean themselves using their rough tongue. Although, the owner can help comb his cat when the breed has long hair. When the cat stops grooming itself, then that is the time that the owner should worry. Feed her small meals throughout the day, as she is can carry around a few kitties in her belly, her stomach will be crampt for space! Make sure you change her to a special diet full of vitamins and minerals to put her in top condition for pregnancy and always have plenty of water available. Find an out of the way place, such as a warm cupboard for mother to be able to escape away before and after birth with the kittens. This is because high end cat foods need a smaller serving amount than the low end cat foods to give a cat all the nutrients they need to be satisfied and healthy. When comparing a premium brand such as Eukanuba, to a lower cost brand such as Purina, the cost difference for the recommended serving size is only a nickel a day. When you have one of these, take it and put it right next to his favorite piece of furniture to destroy. Then, gradually move it away from the furniture as he gets accustomed to it. You can also use a pet repellant spray such as Bitter Apple on the furniture that the pet is clawing at. Take the time to test the spray on a non visible area of the furniture before using it though.
