Application Steps: (We recommend 2 People's Work)
1.Correct size is important. First, take one of the nail caps out and try it on your cat's Claws without the glue. It should fit like a sock.

2.Trim cat claws to the same length with that of the nail caps. If the nail cap is too large, you may trim the open end of the nail cap until it fits. (Note: Do not trim kittens claws before applying nail caps. You will need a sufficient claw surface for the glue to adhere properly.)

3.Fill each nail cap a little glue, only glue in a part of the nail (about 1/3, never fill to too full to prevent overflow of the adhesive), Wait the adhesive is half-dried in the nail cap. (Please be careful and avoid dropping glue on your hands or your cat's fur, if you do, remove it with use nail varnish remover.)

4.Grasp the claws of your cat, slightly push aside the fur around the nail and expose the nail. Put the nail caps onto the claw and make sure they are completely wrapped. Wait until the adhesive is dry and continue with the next nail.

5.After all caps are applied, observe the cat for at least five minutes to make sure nail caps are secure. A good tip is to feed your cat his or her favorite food immediately after applying all nail caps.

Notes:
1.Some cats will try to bite off the nail caps after they are initially put on. If this happens, immediately calm them down. Please don't worry, it is quite normal. Generally, after wearing for the first few times, they will get used to them and without any discomfort. If it is necessary to replace any nail caps, just take off the remaining nail cap materials and clean the nails. Nail caps should always be replaced after 8 weeks.

2.Different cats, different movement and location (such as cement, grass, floor, carpet) etc., different wear rate of the nail caps. Some wearing 3-5 days may wear out. Some can wear 1-2 months or even longer.

3.Addition, the cat nails have scalability, we recommend you leave a little gap out when stick the nails, that cat nails have activity space.
