Summarize this article in one sentence.
Generally, nail caps come in three sizes: small, medium, and large.  These sizes depend on your cat’s weight.  Each manufacturer will define what sort of cat their product is designed for.  Check the packaging carefully when shopping for nail caps to ensure you buy some that fit your cat’s nails.  Additionally, nail caps come in different sizes.  Choose the size that fits your cat’s nails.  To select the size that will fit your cat’s nails, check the nail cap package for information regarding which nail caps are best for a cat of a particular size. Choose a color that you like. Inside the nail cap package, you’ll find a variety of materials.  Every nail cap package is different, but each will probably include nail caps, adhesive, and applicator tips in varying quantities.  Each of these objects will probably be packaged separately.  Open each package in turn so that all necessary materials are ready for use.  You’ll only need one applicator tip and one container of adhesive. You might need to cut the adhesive container’s top off.  In other cases, the adhesive’s lid will simply twist off. Additionally, your nail cap package should include an instruction manual.  Read the instruction manual before applying the nail caps so that you’re aware of the specific directions for use. While it is possible to put nail caps on your cat by yourself, the whole process proceeds much more smoothly if you hold and reassure your cat while a friend or family member applies the glue to the nail cap.  Once the nail caps are ready, you can just slide them on your kitty’s claws.

Summary:
Choose the right nail caps. Ready your materials. Ask a friend for help.
