No. If you look at a whale, it is a mammal but it has a tail and fins and a monkey has 2 arms and 2 legs scientifically classified.
Oh, dude, not all mammals have four legs. Like, have you seen a kangaroo? They hop around on two legs and use their jacked-up tail for balance. And let's not forget about those sneaky dolphins, they're mammals too, but they're all about that aquatic life and don't bother with legs at all. So yeah, not all mammals are rocking the four-leg look.
Insects only have six legs and are not mammals.
a cat has 4 legs
Got No Legs
That would be four.
birds are a separate class by themselves animals with backbones are either birds, fish, mammals, reptiles, or amphibians they are neither mammals or amphibians thery are birds their own class of chordates
Because they are adapted like that for their environment. Four legas help them be able to run fast if they are chasing food or running away from predators. They also need four legs for a better balance because of the uneven environment that most live in. Humans have 2 legs because that is all we need, but when we weren't as evolved we to had four legs to adapt to the environment. We have evolved and 2 of our 4 legs turned into arms because that was more useful for our survival.
