i will be getting a pair of two year old hedgie rescues. they have been together since very young and get along great. the owner has kept them on purina kitten chow forever though. i was wanting to put them on an adult indoor formula. will this cause any issues since they are older. i will do it gradually of course but i am concerned. what food do ya recomend. i tried reading through the food list but found it confusing. so i would love a concesus of waht is being fed by members.
