Declawing of cats involves surgical amputation of the last bone of each toe, causing chronic pain and behavioral changes in many cats.
Declawing amputates the last phalanx of each digit equivalent to cutting human fingers at the last knuckle. Post-operative pain is well-documented. Chronic neuropathic pain affects a significant proportion of declawed cats for life. Behavioral changes including increased aggression and litter box avoidance suggest ongoing discomfort. The procedure is considered unnecessary as alternatives like nail trimming and scratch posts are effective.
