Cat Paw Pad Ulcers From Overgrown Nails
Overgrown or embedded nails can create chronic pressure, puncture wounds, and eventually painful paw pad ulcers. These injuries are often hidden until mobility changes. Understanding how they form helps prevent escalation.
How Overgrown Nails Create Ulcers
When a claw curls inward (often forming a circular “disc claw”), it presses continuously against the paw pad. Constant pressure reduces circulation, irritates tissue, and may lead to penetration. Once the skin barrier breaks, bacteria can enter and create infection.
- Pressure indentation becomes tissue breakdown
- Puncture wound forms beneath nail tip
- Inflammation, swelling, and crusting develop
- Ulceration may deepen without intervention
Warning Signs of Paw Pad Ulcers
- Limping or reluctance to jump
- Excessive paw licking
- Swelling, redness, heat
- Crusting or discharge
- Visible nail tip disappearing into tissue
After Removal: What an Ulcer Looks Like
Clinical Approach
- Controlled, stabilized paw handling
- Safe nail release with minimal tissue trauma
- Sterile flushing of ulcer tract
- Aftercare instructions tailored to wound depth
- Veterinary referral when infection or systemic signs are present
When This Requires Immediate Care
- Rapid swelling or spreading redness
- Strong odor or discharge
- Fever or lethargy
- Refusal to bear weight
- Multiple affected paws

Considering Grooming Without Sedation?
Many cats are referred directly to anesthesia when tolerance feels uncertain. When clinically appropriate, we offer awake, trauma-informed grooming using TANDEM Cat® methodology.
