Are sloths a dangerous animal?
I don't think so. They're so slow they wouldn't be able to catch you! They do have claws, so don't get too close.
No, they're too slow to hurt anyone.
If you cannot run yes ;)
No they sleep a lot and are very slow.
No they are harmless animals that are very slow and sleep a lot. The only defense they have is the fact that they live in the trees. Their claws are just for climbing.
