Do all mammals have udders

No, modern camels do not have hooves. They have a two-toed foot with toenails and a soft footpad. Prehistoric camels may have had hooves. Wait, no prehistoric camels have probley had even less hoof-like feet. Horses have hooves and their ancesters feet had camel like feet with two nails. You see , over time those two toes turned into hooves!So , before the camels had two toes , they most likely had more toes.
