Total litter replacement is required from time to time, but it isn't often necessary. The scoopable litters are, by far, the more convenient product for cat owners. We at The Cat Doctor recommend Everclean Cat Litter. We feel it is the best litter on the market. Everclean also comes in a variety of grades, depending upon the number of cats in your household.
Scratching is a behaviour very natural to cats.
Kittens scratch indiscriminately when they are young. However, as they grow older, they begin to concentrate on one or two favorite areas. Scratching is one way of marking territory. Where you see your kitten scratching is where you must place his scratching post. Once your kitten imprints on the scratching post you can then move it, about 6 inches per week toward a location in the house more desirable to you.
