Your guinea pig needs; - A daily vitamin C supplement in his
water. The flavoured, effervescent vitamin C tablets available
from chemists are best. He needs ¼ of a 500mg tablet made up in
his water bottle fresh every day. Excess vitamin C is excreted
in the urine so you cannot overdose him on this vitamin. - A
tablespoon of a proprietary guinea pig food daily. Do not feed
more dry food than this. The pelleted varieties e.g. Supa Guinea
Excel from Burgess Petfoods are best as this will prevent your
guinea pig from picking out an unbalanced diet. Buy only small
quantities at a time and buy sealed bags rather than scoops from
open bins to preserve the vitamin C content, which degrades
quickly. - Ad-lib good quality grass hay or dried grass. It is
best to purchase a bale from a stables for better quality at a
cheaper price than the packaged hay from pet shops. - Ad-lib
grass, either grazed from the lawn or hand picked. Never give
mower clippings. - Leafy green vegetables e.g. cabbage, spinach,
parsley, broccoli,
