A pet door capitalizes on your busy schedule and your cat's need to roam. Pet doors range from simple entry flaps to automatic models, and come in a wide array of sizes. Most smaller pet doors are suitable for cats. However, you may want to get a strong or lockable door - raccoons and other pests may find your pet door to be a gateway to free food, otherwise. If you own both a cat and a dog, you can use a door as a barrier between them, safeguarding the cat's food, for example.
Scoopable litter is very popular, because of their convenience and ability to contain odors.
Many of these are biodegradable and easily flushable. Odor control has become more effective, with antibacterial litters being the most popular advance in that direction. Other litters create less dust, and make it more difficult for the litter to get tracked into the rest of the house. The always-constant demands for convenience and value have created changes in packaging as well. Less bulky, pourable, and recyclable packages have appeared, as have ones that allow you to bring the container back to the store and refill them.
