What should you not feed your Guinea pig?

The list of what not to feed is so long that it's best to check out each new food before feeding it. For example, avocados and coconut are too high in fat for Guinea pigs, while any form of bean is liable to ferment inside the gut and cause bloat. Absolute no-nos are processed human foods such as cookies, chocolate or candies, which guinea pigs are not designed to eat. Pigs are strictly vegetarian, so never give a Guinea pig meat in any form. Be wary of the onion family and garlic since these can be toxic, and surprising things such as daffodil or tulip bulbs are toxic, so always err on the side of caution and check first before letting your pet chew to its heart's content.
