With words, our tones in our voice can change from time to time, which a cat can become confused with the training. With talking for the commands, a cat could mistake the commands. With using a clicker, it is more of a training tool to get the behavior started with the cat. Then you can put the clicker away for that behavior or trick once a cat has learned the behavior When taking the cat out for a walk or on a trip, the clicker is a good item to carry along with you. As a last resort, you can use a flea and tick bomb in your home. But, in this case, the animals will need to stay out of your home for at least 24 hours. Fleas are a serious concern and you need to keep them from affecting your pet. If your pet has them, also talk to your vet about treatments he can provide as these are professional strengths that can help. Before bringing home the new kitten, take her to your veterinarian to get her checked and vaccinated, kittens have weak immune systems and are likely to pick up something at the shelter or cattery. Consider adopting a cat of the opposite sex to your existing cat, this will avoid same sex rivalry and associated problems. For those who are looking for a cat to provide them with entertainment, these are a good choice. The Rex is a silly cat as it will attempt to amuse you. There are other important features to consider as well. For example, if you want a long haired or a short haired cat. Those who do not have the time to groom the pet daily should not choose a long haired cat. If your cat trusts you, it will probably do what you want, so speak in a calm tone. Your cat can tell if you are anxious, so don t worry if things go wrong. Keep calm and start again. Don t force training on your cat, only attempt it when it seems happy to do so. Don t move too quickly, or the cat might misunderstand. It does not matter whether you get a male or female because their behaviour is not dependent on their gender. Neutered and spayed cats make pleasant companions. Any good animal shelter will have healthy cats available. Remember a cat you picked up from the shelter is actually saved from death by you.
