I have a couple Things

1. For SurvivalGames the pet follows you in to the game
2. Pets travel with you through multiverse portals but i only want them in spawn

please help

1. Does this really have much relevance...? It's not practical to support every single plugin out there (for instance a SG plugin). The Dev API is there for developers to provide their own additions and hooks.
2. See the config file to disable pets in certain worlds.
