Meatball and Lampo are best friends and have a brotherly relationship with each other. Although, Lampo does get slightly annoyed by Meatball's cowardice, immature behavior, his overreacting over things, and even his temptation to eat like the rest of the Buffycats, but still loves and cares about him deeply.
Meatball and Pilou are the best of friends and have a big brother and little sister-like relationship. Although in "Dogsitter Mission", they did argue and fight about who took each other's stuff or even fight over some things, but with Lampo and Milady's help, they easily say sorry and make up with a meaningful hug.
