How can I effectively treat and prevent calluses on my cat's paw?

To effectively treat and prevent calluses on your cat's paw, you can regularly trim their nails, provide soft bedding, and apply moisturizing paw balms. Additionally, ensure your cat's environment is free of rough surfaces that may cause irritation to their paws. Regularly inspect and clean their paws to prevent calluses from forming. If the calluses persist or worsen, consult a veterinarian for further advice and treatment options.
