The AVMA strongly encourages client education prior to consideration of onychectomy (declawing). It is the obligation of the veterinarian to provide cat owners with a complete education with regard to the normal scratching behavior of cats, the procedure itself, as well as potential risks to the patient. Onychectomy is an amputation and should be regarded as a major surgery. The decision to declaw a cat should be made by the owners in consultation with their veterinarian. Declawing of domestic cats should be considered only after attempts have been made to prevent the cat from using its claws destructively or when its clawing presents an above normal health risk for its owner(s).
The following points are the foundation for full understanding and disclosure regarding declawing:
