how to grow up kittens

Kittens are not small puppies. Rules of thumb that apply to dogs do not necessarily apply to cats, and the optimal age for adoption is one of those rules. While the best age to adopt a puppy is 7 weeks, kittens should be at least 9 weeks of age, and some even suggest 12 weeks of age before adoption. Kittens need a longer period of time with their mother and siblings to help them learn normal and acceptable behaviors.
If possible, it is best to choose a kitten from a litter. Observing the interactions between the kittens and the personality of the mother (and father, if possible) may help you choose a kitten with the traits you desire. Though friendly parents may have timid or aggressive kittens if they are not socialized properly, your chance of having a friendly kitten will increase if the parents get along well with people. If the kittens sense fear of people in their mother, they are more apt to be fearful, too. Adopting kittens from a feral (running wild) cat can be very problematic, especially for people who do not have a lot of experience handling cats.
Anyway, if you find a kitten that's really young and you adopt it directly, you will need cat milk in order to feed her, as cats have problems with normal milk.

Breeders sometimes liken the appearance of the early genitals of kittens to punctuation. A female kitten's genitals will resemble an upside-down exclamation point with the vertical vaginal slit below the anus. A male kitten's organ will look more like a colon. Also, the female's vaginal opening is closer to the anus than the male's budding penis, which may have very small lumps between it and the anus, which will develop into testicles.
It will be very difficult to accurately tell the sex of a kitten until it is at least two weeks old, and even then, both experienced breeders and veterinarians have been known to make mistakes.

In selecting a specific kitten, watch how the kittens interact with each other. A kitten should be playful, but not too aggressive. Kittens should be confident, inquisitive, and not reluctant to come to you. Kittens who hiss or hide when approached by humans will be much more difficult to raise into friendly cats. The kitten should not cower or show fear when petted on his head. In this case, the kitten could have been beaten or could have had some other awful experiences, such as being abandoned on an higkway or thrown in a litter bin or river. Try to be patient and let him become familiar with your smell, at first, and with your caressing hands on a second time. Kittens should readily accept playing with you. Take a string along and drag it on the floor. Well-adjusted and healthy kittens should eagerly pounce on it and want to play. Realize, however, if the kittens have just had a rousing game of tag or wrestling, they may be tired. Kittens are often either very active or sleeping, not much in between. They love to play with nearly everything, so be careful not to give them dangerous toys!

In order to be sure that your kitten is healthy, check for some of the things I listed below.. However, always have your kitten checked by your veterinarian, preferably the day you get the kitten.

A healthy kitten should have:
- Clear eyes with no tearing or discharge. The eyes should be fully open, focus normally, and be able to follow your finger or a piece of string dragged across the floor.
- Clean nose with no nasal discharge, sneezing, or labored breathing.
- Clean ears with no odor, head shaking, or scratching. Black granular discharge could indicate ear mites.
- Pink gums, with no sores or ulcers in the mouth or on the tongue. The teeth should be white and properly aligned.
- Clean anal area, with no discoloration, matted fur, of evidence of parasites (tapeworms may look like cucumber seeds).
- Clean and soft coat with no dandruff. There should be no evidence of parasites, e.g., lice or fleas (flea dirt may look like tiny black-red granules, which dissolve into red on a moistened paper towel. There should be no evidence of scratching or bald spots (ringworm). A kitten's coat will usually not appear as glossy as an adult's.
- Symmetrical body shape, and one that is neither too thin nor has a protruding belly, which could indicate a severe intestinal parasite problem.
- Good appetite.
- No lumps or bumps - including at the umbilicus (belly button).
- Coordinated movement, with no head tremors. Some cats may have extra toes (polydactyly), but this usually does not cause a problem.
In case you spot fleas or fear intestinal problems, hear your vet, check his medical prescriptions and choose cat food specific fot the kitten problems:
