HELP NEEDED🐱🐱

5 months ago I adopted a 2 month old kitten now she’s a 7 months old ball of fur and a happy healthy cat. I literally put her needs before mine and I’m happy to think I’m really taking care of her. Last few days I started thinking about adopting another kitten, because I absolutely love cats and my current cat would have a friend. Do you think that’s a good idea? Btw I live in a relatively small apartment by myself and I work full time I’m a lawyer. Am i making a mistake? Also my cat is a little shy, quiet and well behaved.
