Once the litter is registered, each kitten will need to be individually registered by its new owner. There are three categories of recognized cats. They are the Championship Class, the Provisional Class, and the Miscellaneous Class. Each bred that the CFA recognizes is in one of these groups. They must win first place in their breed and then their class before they can compete for the title of best in show. You have the traditional buckle style which is easy to put on and take off but the buckle can break. Then there is the slide through adjustable kind. This is a more secure way of fastening but it s also more difficult to adjust, especially if you have a cat that doesn t like having a collar on. Most cat collars come with an elasticated or a breakaway section. You can use these to feed multiple cats too. There are some disadvantages to using them though. For example an aggressive cat can easily prevent the other shyer cats from getting enough food. It is also harder to know just how much food the cat is eating so you may not realize if he is eating less than he normally does. "One of the most important goals when feeding senior cats is maintaining an ideal weight and keeping that weight stable," said Dr. Arnold Plotnick, who developed a senior wellness program to address the special needs of aging cats at his veterinary clinic, Manhattan Cat Specialists in New York City. Some kittens will hide out under furniture for some days, more adventurous ones will be eager to explore their new home almost straight away. Do not try and force kitty to leave the room, you will know when she is ready. Allow your new kitten to explore around your home while your older cat is in another room. If your cat refuses to use the scratch post, then it may not like the fabric that covers it. Try putting an old piece of clothing that smells like you over the board; put some hemp rope around the scratching tree, or put down some straw mats, cats often like these better. Make sure where your cat sleeps is quiet and comfortable.
