Hares and rabbits are very different from each other.
The hare only belongs to the genusLepus, but their are many genera the rabbit belongs to - Pentalagus, Bunolagus, Nesolagus, Romerolagus, Brachylagus, Sylvilagus, Oryctolagus, Poelagus.
Hares are larger and faster, generally longer ears and have black markings on their fur. Leverets (baby hares) are precocial, which means, unlike rabbits, are able to see almost immediately after they're born. Baby rabbits are called kits, kittens or bunnies. Hares are also have stronger limb muscles. Hares have not been domesticated, so you can't have one as a private pet (yet), or at least legally.
Hares do not neccesarily live in warrens and burrows for protection; they rely on speed for that.
Hares are more solitary and rabbits are extremely social.
I've always found animals easier to befriend than humans they dont judge you,my dogs and cats are always happy to see me,the only thing animals lack is the ability to communicate with us but they do offer a unique friendship that is often overlooked because they are seen as lower lifeforms but I have more respect for animals than humans mostly because we are a rather corrupted species and seem to control over everything on the planet wich will eventually cause mass destruction of many species of animals because we will get bigger and bigger and in the process we will be wrecking the planet for all it's worth
