Personality
Alfie is a happy-go-lucky machine who always loves working. He enjoys playing in the dirt, and often says "More dirt means more fun!" When Jack arrived to the Pack, him and Alfie were instantly good friends, and always helped each other when needed.

Alfie is sometimes teased about his size by Max and Monty, as seen in Alfie has Kittens. He later proved his worth when he saved a family of cats from a destroyed building, and started to realize that being small can be a good thing.
