How to recognize skin cancer in cats
Look for lumps or discoloration.
Skin cancer usually creates an area on the skin that is discolored and raised. When playing with your cat or cuddling up with it, take the time to look over its body for areas of discolored skin.
Also look for areas where the cat's fur is out of place, perhaps due to a growth on the skin underneath. If you find an abnormal area, have it looked at by a veterinarian.
