What’s wrong with your cat’s swollen legs?

There are several types of swollen legs in cats: the first is due to trauma with infection and swelling with pus inside. The second is a fracture due to a violent impact and a large amount of muscle tissue is broken resulting in a haematoma. The third is swelling of the lower limbs due to venous embolism caused by kidney failure. The fourth due to swelling caused by hypoproteinemia.
