There are several possible causes for a swollen foot in cats. Here are some of the most common ones:
Injuries
- Fractures: Cats can break their bones if they fall from a height or are involved in an accident. A fractured bone in the foot can cause swelling and pain.
- Cuts and puncture wounds: Cats may get cuts or puncture wounds on their paws from sharp objects, such as glass or nails. These can become infected and lead to swelling.
- Sprains and strains: Twisting or overstretching the foot can cause sprains or strains, resulting in swelling.
- Abscesses: Bites or scratches from other animals can lead to abscesses, which are pockets of pus that cause swelling and pain.
- Foreign objects: Thorns, splinters, or grass seeds can get stuck in the paw and cause irritation and swelling.
Infections
- Bacterial infections: Infections can occur due to cuts, bites, or other wounds. Bacterial infections can cause redness, swelling, and pain.
- Fungal infections: Fungal infections, such as ringworm, can affect the paws and cause swelling and itching.
- Parasitic infections: Mites or fleas can cause skin irritation and swelling in the paws.
Allergies
- Food allergies: Cats can be allergic to certain foods, which can cause swelling in the paws.
- Environmental allergies: Allergies to pollen, dust, or other environmental factors can also lead to swollen paws.
Autoimmune Disorders
- Feline plasma cell pododermatitis: This is an autoimmune disorder that causes the paw pads to swell and become painful.
- Eosinophilic granuloma complex: Another autoimmune disorder that can cause skin lesions and swelling in the paws.
Other Causes
- Arthritis: Arthritis can cause joint swelling and pain in the paws.
- Nail overgrowth: Overgrown nails can cause irritation and swelling in the paw pads.
- Edema: Fluid accumulation in the paws can cause non-painful swelling.
- Bone diseases: Rarely, bone diseases such as bone cancer can cause swelling in the paws.
If your cat has a swollen paw, it is important to take it to a veterinarian for a proper diagnosis and treatment.
