PetJoy is not a valid member of Player "Players.garfird1231" error?

I'm trying to make it that if you pet your pet dog, it will give you money and +2 of joy. There is also joy, where it decreases by 1 every second. But whenever I try to pet the dog, it gives the error.

Code for the services

local HungerDecrease = 1
local joydecrease = 1

game.Players.PlayerAdded:Connect(function(Player)
	
	local PetHunger = Instance.new("IntValue", Player)
	PetHunger.Name = "Hunger"
	PetHunger.Value = 100
	
	Player.CharacterAdded:Connect(function()
		PetHunger.Value = 100
	end)
	
	while wait(HungerDecrease) do
		PetHunger.Value -= HungerDecrease
		workspace.Doge.hunger.TextLabel.Text = "Hunger: "..PetHunger.Value
		
		if PetHunger.Value == 0 then
			Player:Kick("Doge starved")
		end
	end
end)

game.Players.PlayerAdded:Connect(function(Player)
	local PetJoy = Instance.new("IntValue", Player)
	PetJoy.Name = "Hunger"
	PetJoy.Value = 100

	Player.CharacterAdded:Connect(function()
		PetJoy.Value = 100
	end)

	while wait(joydecrease) do
		PetJoy.Value -= joydecrease
		if PetJoy.Value == 100 then
			workspace.Doge.joy.TextLabel.Text = "Joy: Very Happy"
		end
		
		if PetJoy.Value == 75 then
			workspace.Doge.joy.TextLabel.Text = "Joy: Happy"
		end
		
		if PetJoy.Value == 50 then
			workspace.Doge.joy.TextLabel.Text = "Joy: Bored"
		end
		
		if PetJoy.Value == 25 then
			workspace.Doge.joy.TextLabel.Text = "Joy: Sad"
		end
		
		if PetJoy.Value == 0 then
			Player:Kick("Doge is depressed")
		end
	end
end)

code for petting your pet

local Doge = script.Parent
local PSS = game:GetService("ProximityPromptService")
local bark = Doge.dogbark

PSS.PromptTriggered:Connect(function(prompt, player)
	if prompt.Name == "Pet" then
		local PlayerCash = player.leaderstats.cash
		local PetJoy = player.PetJoy
		
		PlayerCash.Value = PlayerCash.Value + 1
		PetJoy.Value = PetJoy.Value + 2
		bark:Play()
	end
end)
