MySQL Error Code: 1064 Stored Procedure Syntax Error near END END

I am very new to MYSQL programming, I need to create a stored procedure that adds an animal to the animal table, but need to check that foreign keys exist in the Catagory table (catID) and the Area table (Areaid).

This is what I have so far, but I get an error that says a syntax error next to END END, I tried to put parentheses, but then there are only more errors.

If anyone can help, that would be great!

-- checking if the SP already exists and deletes it
DROP PROCEDURE IF EXISTS sp_AddAnimal;

-- creates the stored procedure to add animals to the Animal Table
