What are the common signs and symptoms of cancer in cats, and how can I tell if my cat's limping is related to cancer?

Common signs and symptoms of cancer in cats include lumps or bumps, changes in appetite or weight, difficulty breathing, and lethargy. If your cat is limping, it could be related to cancer if the limping persists, is accompanied by swelling or pain, or if your cat is also showing other signs of illness. It is important to consult with a veterinarian for a proper diagnosis and treatment plan.
