Research overview: declawing biomechanics and welfare consequences in domestic cats

Declawing, or onychectomy, removes not just the claw but the terminal toe bone, and this overview surveys its biomechanical and welfare consequences. Because the claw grows from that bone, eliminating the claw permanently requires amputating the last digital segment, altering weight-bearing, gait, and the paw normal mechanics. Research and clinical literature document potential long-term effects on posture, pain, and behaviour, informing veterinary positions and legal bans in many regions. Investigators draw on surgical outcome studies, gait analysis, and behavioural assessment. Why it matters: the procedure illustrates how deeply the claw is integrated into toe anatomy, why it cannot be removed like a fingernail, and how understanding feline foot biomechanics underpins evidence-based welfare policy for companion cats.
