Cartel Market pets originally come from the Cartel Market, either through direct sale or through random chance in Cartel Packs. Almost all Cartel Market pets are cosmetic in nature, they give no special perks that other pets won't also give you. Cartel Market pets can sometimes be found for direct sale on the Cartel Market, but if it is not available there it can be purchased from other players on the GTN. If you can't find it on the Cartel Market which is run by the developers who rotate items in and out over time, and can't find it listed on the GTN which is made of listings created by players, you're looking for an item that is currently considered rare or uncommon, and you'll either need to keep checking back those two places, or try posting in the /trade chat or the Fleet General Chat that you are looking to buy one - but it will likely be very expensive if no one has one listed on the GTN already!
