Which Plants are Toxic for Guinea Pigs?| Toxic Plants for Guinea Pigs

Do you have knowledge about toxic plants for guinea pigs ? Guinea pigs are a lot like chefs by nature and they are able to savor so many different flavors in their diet. You want to make sure that you’re doing all you can to provide your little pals with lush green grass as well as a variety of nuts and seeds which combine health, happiness and taste. By doing this, you’ll be creating a world where your pets feel right at home.

Guinea pigs possess excellent olfactory senses. Any odoriferous plants that have strong fragrances are not good for guinea pigs. Plants like marigold (Calendula officinalis L.) or catmint (Nepeta cataria L.) have strong scents that can be harmful to our pets. Other plants such as pepper (Capsicum annuum L.), henbane (Hyoscyamus niger), yew-leaves from a certain yew species and wormwood (Artemisia absinthium L.) are also toxic because of their leaves and stems which contain poisonous alkaloids.

In order to keep them healthy, we have to make sure that guinea pigs eat the right foods. Their metabolism is slow and their bodies can’t exactly process what’s not meant for them, so if something toxic accidentally goes into their system, they are in real danger.
