Dogs and cats have very different nail clipping needs. With dogs, you want to watch for when the nails have grown long enough to touch the floor. If you hear your dog’s nails clicking on the ground or if they begin to grow sideways, it’s time for a trim. Ideally, you should be able to slip a piece of paper between your dog’s nails and the floor. Cats can retract their claws and bring them out only when needed. Because of this, outdoor cats should not have their nails trimmed as they need their claws to serve important functions like climbing, scratching, and marking their territory.  Indoor cats should have trimmings done every 10 to 14 days. Every cat is different, your vet can help you determine the best schedule for regular feline nail clippings.
