Loud colorful painted packages from the pet shop contains almost junk food – so leave it for a proper diet! Guinea Pigs really love cheap and healthy natural finish food.
Natural food is always the best choice you can offer for your cavies. It isn’t quite ambitious or expensive to feed them responsible. Far from it, a good diet might be much cheaper at some seasons if vetgetables are cheap and grass is rising high. The nourishment of cavies stands on the ground of grass and other ground based dibbles / shrubs. A diet must not contain any animal products like animal fat or industrial fall-out like molasses.
And Guinea Pigs are not your trash can for kitchen waste! Ask yourself: Would you prefer to eat it? If not, don’t give it to them as well.
