Essential fatty acids (like omega 3 and omega 6 fatty acids) and fat soluble vitamins (Vitamin A, Vitamin E, Vitamin, D, Vitamin K). The plain fat is a nutrient too.
Kittens, generally, can begin to use a litter box at about four weeks of age, and a kitten being raised without its mother or adult cat will take slightly longer to litter train; so, keep this in mind when you begin the task of litter training your kitten. - Place the kitten in the box 1/2 hour after play or meals.
1 As your kitten grows, you will need to put more litter in the pan. 2  By the time your kitten is six months old, you should start placing two to three inches of litter in the pan. 3  It's best if you have a house with tile or wood flooring because that way the pee can be mopped up.. Clean the litter every day. Kittens do not like to relieve themselves in dirty areas. If you don't change the litter, the kitten may find a cleaner place, like the carpet, to do her business. 1  To clean the litter box, scoop the waste out of the box, place it in a small baggie, close the bag, and throw it away.
