We live in Uganda and there's only one place that sells pellets; this is alfalfa and comes in 70kg bags only so it goes off before we can use them all for our two buns! Our rabbits eat lots of grass from the garden, have hay all the time and greens twice a day, plus the odd carrot etc. I give them pellets at night so they have something to keep them occupied while they're in their hutch. The other use for having pellets is for when we go away- it's easier than someone temporarily looking after them having to find extra odds and ends for them. But are pellets necessary with the other things in their diet?
