First, read the English article below.

You can't trim your cat’s nails whenever you feel like it. You should pick a time when your cat is feeling nice and relaxed, such as when it's just coming out of a nap, getting ready to nap, or calmly resting on its favorite surface during the day.  Another good time for nail trimming is after your cat has eaten and is feeling sleepy and content. Don't try to trim your cat's nails right after play time, when it’s hungry, when it's restless and running around, or in an otherwise aggressive mood. The cat will be far from receptive to you trimming its nails. You may see that your cat has a broken or splitting nail and will want to cut it instantly, but don’t. Make a note of it and wait for your cat to get relaxed before trying to cut it, or you could make it worse. Before sitting down to cut your cat’s nails, be sure you have the right equipment to do so. To trim your cat's nails, you’ll need a pair of nail clippers designed to clip cat claws and a styptic pencil.  There are several different styles of nail clippers, all of which largely do the same job. The most important thing is that the clippers are sharp, so they snip straight through the claw. Not only will using dull clippers make the job longer and harder, but you may also end up squeezing the quick, which can be painful for the cat. There are two primary styles of clipper: scissor and guillotine clippers. Scissor clippers cut a cat’s nails using a scissor motion and usually come in small and large sizes. The small “nippers” tend to be better for those new to clipping nails or if you just need to snip the tips. Larger scissor clippers are suited to cutting older, tougher nails. Guillotine clippers use a sliding blade that cuts the nail when you squeeze the handles together. The claw fits into a slot and the blade slides across to clip the nail. These are strong clippers that are good for cutting long, thick nails (but not overgrown nails--large clippers are better suited to that). If the clippers are sharp the cat won't feel the quick clip.
