Why do rabbits, guinea pigs, chinchillas, and degus forage? Foraging is a natural, instinctive behaviour that's essential for their physical health and mental wellbeing, not just a way of finding food. This guide from HayDay explores how these small herbivores forage in the wild, what drives their behaviour, and how you can recreate it at home to keep your pet happy and healthy.

Key Points on Foraging Pets
-
Foraging behaviour is vital for the physical and mental health of small pets.
-
Foraging means "searching for food", and this natural instinct should be replicated at home for domestic pets.
-
Pets that forage spend more time searching, eat more slowly, and eat more appropriate food, reducing the risk of becoming overweight or unwell.
-
Both solitary and group foraging strategies play a role in shaping natural behaviour.
-
Owners can recreate wild food sources and enrich living spaces with a variety of foods to support these instincts.
What Is Foraging Behaviour in Small Animals?
Foraging is the natural process of locating, obtaining, and eating food while managing risks like predation, and it's directly tied to survival and reproductive success in the wild. Wild rabbits, guinea pigs, chinchillas, and degus rely on fibrous plants, grazing grass, and digging to stay healthy, and this instinct doesn't disappear once they become pets.
Foraging behaviour supports three key areas of health:
-
Dental health: constant chewing on fibrous foods wears down ever-growing teeth
-
Gut health: fibre intake supports healthy digestion
-
Mental enrichment: searching for food prevents boredom and reduces stress
Replicating these natural behaviours at home is essential for keeping pet rabbits and guinea pigs both physically and psychologically well.
How Can You Encourage Natural Foraging at Home?
You can encourage foraging by hiding food, mimicking wild diets, and avoiding overfeeding, three simple changes that make a big difference to a pet's daily routine.
Providing enrichment: Hide pellets or leafy greens within hay or feeders to encourage exploration and mimic the challenge of searching for food in the wild.
Mimicking wild diets: Aim to provide an unlimited supply of high-quality hay for fibre, fresh vegetables and herbs for variety, and safe outdoor plants, branches, or leaves where possible.
Avoiding overfeeding: Too many pellets or too much fruit reduces a pet's natural drive to forage, which can lead to obesity and other health issues. Stick to a balanced diet built around hay, with pellets and leafy greens kept to sensible portions.
What Forage Products Help Support Natural Foraging?
HayDay's forage mixes are designed specifically to encourage natural foraging behaviour in mature rabbits, guinea pigs, and chinchillas. Developed with our in-house nutritionist Briony, each mix is made from 100% natural ingredients to add variety, enrichment, and encourage healthier eating habits.
-
Floral Forage: a colourful, high-fibre blend of parsley stalks, raspberry leaves, nettle, dandelion, and cornflowers, ideal for sprinkling over hay.
-
Herbal Heroes: an aromatic mix of chamomile, echinacea, and raspberry leaves that supports natural foraging instincts.
-
Wildflower Wonder: a mix of wildflowers like chamomile and rose petals alongside nutritious alfalfa and parsley stalks.
All three mixes encourage natural foraging, use 100% natural ingredients, and add variety to your pet's daily diet. Use them alongside our premium hay range to get pets foraging (and eating) more consistently.

Do Small Pets Forage Alone or in Groups?
It depends on the species: guinea pigs and degus typically forage in groups, while rabbits can forage both alone and socially. Group foraging improves food discovery and safety, since guinea pigs and degus benefit from shared vigilance against predators in the wild, making their foraging more efficient overall.
How Does the Environment Affect Foraging Behaviour?
Resource availability and predation risk both shape how these animals forage, and each species has adapted differently:
-
Rabbits graze on grasses and leafy plants
-
Guinea pigs forage on low-lying vegetation
-
Chinchillas consume sparse vegetation suited to arid environments
-
Degus balance their diet between seeds, bark, and leaves
Wild foraging patterns are also shaped by the need to avoid predators, with animals adjusting feeding times and locations to reduce risk. Providing plenty of hiding spaces for pets at home helps replicate this natural protective instinct.
What Is Optimal Foraging Theory?
Optimal foraging theory explains how animals choose to forage in ways that maximise energy or nutrient gain while minimising time, effort, and risk. It predicts which food sources animals prioritise and when they'll move on as resources decline, and it applies directly to rabbits, guinea pigs, chinchillas, and degus.
For example, wild chinchillas optimise intake by foraging on sparse but nutrient-rich plants, while degus split their time between ground-level grazing and climbing shrubs to reach seeds and leaves.
How Have Small Pets Adapted for Foraging Success?
Physical traits like strong incisors and efficient digestive systems, combined with behavioural flexibility, are what make these species such successful foragers. Degus, for instance, are obligate group foragers that rely on social cooperation to access shared resources, while chinchillas maximise energy intake by targeting nutrient-dense plants suited to their arid natural habitat.
Frequently Asked Questions
Why is foraging behaviour important for small mammals?
Foraging supports dental health, digestion, and mental wellbeing by encouraging natural instincts and preventing boredom.
How does optimal foraging theory apply to pets?
It explains how animals balance energy and nutrient intake against effort and risk, helping them forage as efficiently as possible.
What are some easy ways to encourage foraging in captivity?
Hiding food, using puzzle feeders, and offering safe chewable foods all help recreate natural foraging behaviours at home.
Foraging behaviour in rabbits, guinea pigs, chinchillas, and degus reflects instincts shaped over generations in the wild. Offering a variety of foods, presented in engaging and challenging ways, is one of the simplest steps you can take to support your pet's long-term physical and mental health.
