What I would do was just start feeding them, and make sure they see you feeding them and they will just slowly graduate to letting you get closer to them. Then what i would do was get some cat treats and hold it out to them, soon they will realize you will not hurt them.
newborn kittens like most newborn mammals do best with milk from its mother. They are not yet ready for solid foods.
If its in another persons garden I suggest you tell them. The best way to catch cats is to lure them out with milk or cat food and trap them in a box.
Newborn kittens need their mother's milk right from birth. If you are absolutely positive they aren't eating, the best immediate solution is to buy replacement formula at Walmart and use an eye dropper or a turkey baster to deliver the milk. NEVER EVER USE DAIRY MILK. Kittens CANNOT digest it and will develop serious health issues. If worse comes to worse, take them to a vet.
The best thing done for newborn puppies is to let the mother clean them up and take care of them,and let them and Mother bond.
nursing from the mother
There is a few way to get rid of stray cats and kittens that is hanging around your house. The best way to get rid of them would be to call your local pound.
Let the mother feed them, that's the best option.
* You can bottle feed them. Call your local veterinarian and see what is the best formula for the age of your kittens.
Yes it is ok. Kittens can't get hurt or sick unless your hands are dirty or you drop the kitten. But it would be best not to take it away form its mom for long. The kitten needs to eat the milk the mom provides.
It is best to bring the cat and her kittens inside the house to protect her from temperature extremes and other animals. Newborn kittens can't regulate their body temperature and they need to be in a warm room (75 degrees, ideally) without drafts. A box that you cut a hole in lined with blankets or old towels will make a comfortable nursing nest for the mother cat and her babies. The box should be placed in a dark or dimly lit room that doesn't get lots of foot traffic - a closet would be good as long as the mother has access to a litter box and food and water. The kittens should be left alone with their mother for the first week, as they need to nurse almost round the clock. The kittens shouldn't be handled at all in the first week or the mother may get too stressed from having her nest disturbed.
Kittens should stay with their Mom until at least 10 weeks, thoroughly weaned. They learn all their skills from Momma Cat so never feel the rush to take them from the mother, as this can lead to serious problems for the kittens in later life.
Most baby kittens do not require eye care unless there is a discharge such as pus or blood. As baby kittens are very sensitive to chemicals, the best way to treat discharge is by using a damp, warm towel, and lightly cleaning the area. A Veternarian may also give a baby kitten antiobiotic eye drops, or wipes specifically for newborn and small kittens.
