hi all, only had bumble n bee (6-8week old sows) for 3days so new to this, wondering how many hours most guinea pigs sleep and when? they've been fed twice a day approx 9-10am and 7-8pm but feel i might be disturbing their sleep in the morning, should they be sleeping at these times? and also there is always food left over, how much should i be giving them? i am giving 2 fresh bowls of guinea pig nuggets each feeding at the moment, but they seem to eat mostly hay. also what kind of fruit n veggies are best and how often should i feed them these? any info will be appreciated
