I would keep the name Snuggles. I think its a cute name! If you want to change it, some suggestions are Fluffy, Caramel Cream (I think his colors look like caramel cream!), Creamy, Snowflake, Peanut Butter, Ginger, and Cocoa. The guinea pig is really cute! I hope you'll enjoy many years together with that cute little furry kid!
