Would a OOP be useful for making a pet system?

OOP

local pet = {}

pet.__index = pet

function pet.new(name, type) -- Type, could be Cat, Dog, Fish etc
    local petObject = setmetatable({}, pet}

    petObject.name = name
    petObject.type = type

    return petObject
end

function pet:GetName()
    return self.name
end

function pet:GetType()
    return self.type
end

function pet:FollowPlayer(player)
    -- Code here
end

return pet

If I'm correct, you could do something along the lines of this.
