I only have two piggies, but i think i prefer it that way, when i had 3 pigs in two separate cages i was always having to chose between what cage had a what, unless i bought multiples which became expensive, and just having to divide things, i would always worry one cage would have more than the other and felt sometimes i was leaving one pig out or something (silly i know), so personally i prefer just having one cage with two little piggies to completely spoil rather than having to share everything or spend less on each pig, i can put all my money on my two little princes, plus they take up enough of my time with just the two of them, i don't know if i'd be able to find the time for anymore!
