Have Cat Questions? Ask a Cat Vet Online.
Where on the body does she lick the most?
Any hoar loss? If so where?
Is the skin healthy or does she have sores, scabs, etc?
Thank you for the extra information.
It is important to know that grooming comes in second place to sleeping in a cat's daily activities. Grooming can however reach compulsive levels for some cats. Much like people who bite their nails.
The good news is there are no obvious signs of any coat or skin problems from her habits. Many cats will go bald from over grooming.
Over grooming is many times from anxiety or stress. Relieving any of these unpleasant feelings can help. Toys, play, climbing trees, window perches, etc. can help. It also relieves boredom which can be a trigger to anxiety.
Using a cat pheromone called Feliway can help reduce stress and anxiety too. You can find this at Pet Smart and many larger pet supply stores.
If any skin or coat abnormalities start, then get her a check up with your vet.
