Overgrown and Abnormal Nail Growth in Cats





Cat claw disorders

As cats age their claws can become thickened, brittle and overgrown, and eventually curl in on themselves, cutting into the paw pad. The claws on the front feet are most commonly affected.  There are a number of reasons your cat’s claws may overgrow as he ages.

Poor circulation:

  • As the cat ages, circulation decreases, which has an impact on nail growth. Poor circulation can lead to decreased nutrients reaching the claw bed which leads to abnormal claw growth.

Medical conditions:

  • Diabetes, due to poor blood circulation to the claws.
  • Hyperthyroidism can lead to excessive growth and thickening of the claws.
  • Arthritis may prevent your cat from scratching (known as stropping)  which removes the old/outer sheath of the claw.  In fact, it is quite common for senior cats with arthritis to have difficulty with overall grooming, which includes attention to the claws.

Trimming cat claws

Not all senior cats will develop thickened and overgrown claws, but if they do, they will need to be trimmed to prevent overgrowth. If they are not trimmed regularly they can grow long enough to curl back on themselves and embed in the paw pad which is extremely painful and has the potential to cause an infection.

Some cats are happy to have their claws trimmed, others can be tricky, particularly if you have an arthritic cat. Handling the legs and feet can cause him a great deal of pain which will make the experience traumatic for him as well as yourself.  I have found the easiest way to trim claws on cats who don’t like it is to wait until they are sleeping and then gently cut one or two claws at a time. I have found that normal nail clippers tended to crush and splinter the claws on cats with overgrown claws, again due to their thickness and how dry and brittle they can become. It is worthwhile investing in a good quality pair of nail clippers designed for pets (or even dogs, as they tend to be stronger and sharper).

If you have problems trimming your cat’s claws, a veterinarian or pet groomer will be able to help you.  It really should only take five minutes every 4-6 weeks and at minimal cost.

Other tips for senior pets

A cat is considered senior from 10-12 years of age, which is 57-65 in human years. Visits to the veterinarian should increase to every 6 months, even if your cat appears in good health. This can help to pick up any diseases which are known to affect older cats early. Common disorders in older cats include:

  • Diabetes
  • Kidney disease
  • Hyperthyroidism
  • Arthritis
  • Senility
  • Gum disease
  • Cancer
  • Vision and hearing can also decline as your cat ages
  • Constipation

Many of these can be managed fairly easily, particularly if caught in the early stages.
