Always ensure the right size by trying a cap on your pet's nail without adhesive, it should fit snugly. We will provide full support if the caps do not fit purrfectly.

1. Trim your cat's nails - kitten claws do not need to be trimmed.
2. Than try on the nail cap, without glue, to ensure a proper fit; it should fit snugly.
3. Once you have the correct size, simply fill each nail cap 1/3 of the way full with the provided adhesive with applicator tip, and gently slide the cap onto the nail.
4. Finally observe your cat for 5 minutes until the adhesive sets and you're done !

Kitten Size: Less than 6 months old
These will fit most kittens by the time they reach the age of 16 weeks (4 months). Some kittens can wear them as early as age 12 weeks (3 months). To test, try a nail cap on first without the adhesive. If it looks too big, don't glue it on. The nail cap should fit snugly, like a glove. Kitten nails do not need to be trimmed.

Small: Approximately 6 months old -- Approximately 6-8 pounds
Some kittens at 5 months may need the small size if they are growing fast or are large-breed cats.

Most adult average size cats wear medium. 

Large: Approximately 14 pounds and up
