-# Assignment 2 - Caesar Cipher
-
-This is my code for the OOP homework. I chose the Caesar Cipher Helper.
-
-- **Link:** https://www.codewars.com/kata/526d42b6526963598d0004db
-
-### How it works:
-- The `CaesarCipher` class takes a `shift` number.
-- `encode` changes text to uppercase and moves letters forward. It uses `% 26` so letters stay in the A-Z alphabet.
-- `decode` moves letters backward to fix the text.
-- Spaces and punctuation do not change.
-
-### Tools:
-I set up black and ruff with pre-commit hooks. They check and fix my code format before every commit.
+The `Animal` base class sets up the `name` attribute.
+- The `Cat` class inherits from `Animal` so it automatically gets the name property.
+- I added the `speak` method to the `Cat` class to make it return a str.
