Foraging for Guinea Pigs: Safe Weeds & Plants

Foraging involves searching for and gathering wild food, meaning you can provide your guinea pigs with fresh, nutritious meals at no cost. Over the past few years, I’ve enjoyed countless hours foraging for my guinea pigs, and it’s from this experience that I’ve written this guide. 

You’ll learn about the benefits of foraging for your guinea pigs, discover the wild plants and weeds they can safely consume, and the best places and times of year for foraging. I’ll also provide practical tips and highlight the essential equipment needed for a successful foraging trip.

Benefits of Foraging for Guinea Pigs

Foraging offers numerous advantages for both you and your guinea pigs:

  • Freshness and Variety: Guinea pigs relish the fresh taste and enjoy the diverse flavours and textures of foraged food.
  • Cost Savings: Foraging reduces the need to buy supermarket vegetables, making it a cost-effective option.
  • Nutritional Value: Freshly picked, foraged foods are richer in vitamins and minerals, particularly vitamin C, essential for guinea pig health.
  • Outdoor Activity: Foraging provides an enjoyable outdoor experience that benefits your mental health and well-being.
  • Family-Friendly: This activity can be both fun and educational for children, though supervision is necessary to ensure their safety and the food’s suitability for guinea pigs.
  • Learn About Nature: I’ve become more interested in plants and nature in general since foraging for my guinea pigs.

Watching your guinea pigs tuck into a pile of fresh free food that you have picked yourself is truly rewarding.

Weeds & Wild Plants Guinea Pigs Can Eat

Foraging can be a treasure hunt for a variety of plants and weeds that are both safe and enjoyable for your guinea pigs. Here’s a list of plants, weeds and trees you can look for:

  • Blackberry and Raspberry: Young leaves and fruit (give fruit in moderation as a treat).
  • Broad Leaf and Narrow Leaf Plantain: Very common, nutritious leaves.
  • Burdock: Leaves.
  • Chickweed: Loved by guinea pigs, but avoid confusing it with similar-looking poisonous pimpernels.
  • Cleavers (Sticky Weed/Goosegrass/Bedstraw/Sticky Willy): Leaves and stalk, best before flowering.
  • Clover (Red and White): Flowers, leaves, and stalks.
  • Coltsfoot: Leaves and flowers.
  • Common Groundsel: Flowers, leaves, and stalks, but check for fungus or rust.
  • Common Hogweed: Leaves, not to be confused with toxic giant hogweed.
  • Common Vetch: Leaves, stalks, seed pods, and flowers.
  • Dandelion: Leaves and flowers, a guinea pig favourite.
  • Dead Nettles, Henbit Dead Nettle and Stinging Nettles: Stinging nettles should be dried to remove the sting; dead nettles are safe as is.
  • Grass: Nutritious but ensure it’s free from contamination and poisonous weeds.
  • Ground Elder: Young leaves only, before flowering (don’t confuse with the Elder tree).
  • Hawthorn: Leaves, softer stems, and berries (thorns removed).

  • Herb Robert: Leaves, stalks, and flowers.
  • Mallow: Leaves, stems, and flowers.
  • Meadowsweet: Leaves and stems.
  • Pineapple Weed: Leaves, stems, and flowers.
  • Shepherd’s Purse: Leaves, seed pods, and stems.
  • Sow Thistle: Leaves, stems, and flowers. The spiky sow thistle can also be harvested but it’s best to wear gloves.

When foraging, always positively identify each plant to ensure it’s safe for your guinea pigs to consume. Some easy ones to start with are dandelions, sow thistle, vetch, plantains and cleavers.

Many of these plants are included in my Guinea Piggles Forage Guide, an e-book which includes how to identify 20 weeds and plants with colour pictures and lots of info on each.

Where to Forage

There are many places to find free food for your guinea pigs. Here are some of the best places to look:

  • Hedgerows: Often abundant with wild plants suitable for guinea pigs, including Dandelion, Yarrow, Meadowsweet and Sow Thistle.
  • Cliff Paths: Many plants, including Coltsfoot, Yarrow, Chickweed and Vetch, can be found here.
  • Fields: Open areas are ideal for finding edible plants, particularly Dandelions, Narrow-Leaf Plantain and Common Hogweed.
  • Parks: Public parks can be rich in diverse flora and sometimes have apple trees and bramble bushes. Dandelions and plantains are commonly found in parks.
  • Meadows: Ideal for finding a wide array of wild plants that guinea pigs love, including Clover, Plantain and Grasses.
  • Woodlands: Offer a variety of leafy plants and herbs such as Herb Robert, Dead Nettle and Ground Elder.
  • Your Garden: A convenient source of foraged foods, provided it’s free from pesticides and chemicals. Some of the plants you might find are Nettles, Dandelions and Plantains.
  • Urban Areas: Even in cities, there are spots like parks, around playgrounds, community gardens, and along railways where wild plants can thrive including Sow Thistle, Groundsel and Cleavers.
  • Near Rivers, Streams & Lakes: Some plants such as Herb Robert, Coltsfoot and Chickweed thrive in damp soil.

Regardless of the location, it’s vital to ensure that the areas are free from pesticides and herbicides and not frequented by many pets or wild animals to minimise the risk of contamination. Always forage from areas you know are clean and safe for your guinea pigs.

When to Forage

The timing of your foraging trips influences the diversity and abundance of plants available for your guinea pigs. Here’s a guide to the different seasons:

Spring (March, April, May): This is when many weeds and wild plants start to appear. March marks the beginning of the foraging season, with a wider variety available by April.

Summer (June, July, August): A peak time for foraging, with a plethora of plants in full growth, offering a rich variety of options for your guinea pigs.

Autumn (September, October, November): While some plants start to decline, others continue to thrive, providing a continued source of food into the early part of the season.

Winter (December, January, February): In the UK, foraging becomes challenging during these months, as fewer wild plants and weeds are available.

I enjoy foraging from March to October, rarely buying shop-bought veggies for my guinea pigs. I take a break during the winter but eagerly anticipate the spring when my foraging trips can begin again.

Foraging Tips & Guidelines

For the best foraging experience, here are some tips and guidelines to follow:

  • Stay away from areas that might be treated with herbicides or pesticides.
  • Avoid foraging near animal waste from dogs, cats, or livestock to prevent contamination.
  • Do not forage near busy roads; opt for quieter, less polluted areas.
  • Choose younger leaves as they are often more nutritious and tastier than older ones.
  • Avoid plants that have gone to seed as they can be bitter; pick them before they seed.
  • Accurately identify plants to ensure they are safe; many plants look alike, and some are poisonous.
  • Only pick what you need and do not uproot plants. Harvest where plants are abundant to support local wildlife.
  • Forage only in public spaces and avoid trespassing on private property.
  • Only collect plants that look healthy; avoid any with signs of fungus, mould, mildew, or rust.

Following these guidelines will help you forage responsibly and safely, ensuring that you gather the best possible food for your guinea pigs while respecting the environment and local ecosystems.

Foraging Equipment

Having the right equipment can enhance your foraging experience, making it easier and more efficient. While not all items are essential, they can be extremely handy:

  • Scissors or Secateurs: These are useful for cutting plants with ease, helping to avoid uprooting the plant and ensuring a sustainable harvest.
  • Protective Gloves: A good pair of gloves can protect your hands from stinging nettles, thorny branches, or rough plant material.
  • Foraging Bag or Basket: Opt for fabric, mesh or canvas bags, or a trug basket. Plastic bags in hot weather can cause the forage to sweat. Consider having an extra small bag for plants you’re unsure about to keep them separate.
  • Magnifying Glass: This can be handy for examining small, distinguishing features on plants, helping in correct identification.
  • Guinea Pig Forage Guide: My printable e-book with pictures and descriptions of safe plants can be invaluable for identifying and confirming the suitability of plants for your guinea pigs. It also contains a treasure hunt forage sheet activity for kids.

Feeding Foraged Plants to Your Guinea Pigs

After gathering foraged plants, ensure you introduce them safely to your guinea pigs’ diet. Here are some guidelines:

  • Always clean the plants thoroughly to remove any dirt or potential contaminants before feeding them to your guinea pigs.
  • Start with small amounts to allow your guinea pigs’ digestive systems to adjust to the new foods.
  • If your guinea pigs seem hesitant to try the foraged food, don’t worry. They may need some time to get accustomed to new flavours and textures.
  • Ensure you have accurately identified all foraged items to prevent feeding harmful plants. Even with careful identification, it’s crucial to know the symptoms of poisoning in guinea pigs. Familiarise yourself with these signs and the immediate emergency treatments available.
  • If you suspect your guinea pig has consumed something toxic, contact your veterinarian immediately for an emergency consultation.

By following these steps, you can safely introduce foraged plants into your guinea pigs’ diet, providing them with a variety of natural, nutritious foods while being prepared to act quickly in case of any adverse reactions.
