Rabbit and Guinea Pig Nutrition

Rabbits are herbivores with a digestive system adapted to a fibre-rich diet. Good-quality grass hay should generally be available continuously, supporting normal chewing and gut function. The appropriate hay and feeding plan can vary with age and health, so seek advice for young, elderly or medically vulnerable rabbits. Hay should be clean, dry and free of mould or musty odour. A rabbit that suddenly eats less hay is not simply being fussy; dental discomfort or illness may be involved and deserves attention.

Pellets are a measured part of the diet, not a substitute for hay. Choose a suitable plain product and avoid mixes that encourage selective eating of colourful pieces while leaving other components. Leafy greens can add variety, but introduce them gradually and use safe options appropriate to the individual rabbit. Wash produce and remove leftovers before they spoil. Fruit and sugary treats should be limited rather than used as routine rewards. Fresh water must remain readily accessible in a clean bottle or bowl that the rabbit can use comfortably.

Introduce any new food in small, cautious steps and observe appetite and droppings. Avoid sudden changes, large servings of unfamiliar greens or replacing hay with treats. If loose stool or reduced intake occurs, stop the new item and seek advice, particularly if the rabbit seems unwell. Do not use a restrictive diet to manage weight without professional guidance; rabbits need fibre and adequate nutrition. Food labels and internet lists may not account for a rabbit’s age, medication or health condition.

Monitor the amount eaten and the size, number and appearance of droppings. Reduced or absent droppings, loss of appetite, a hunched posture, tooth grinding or unusual quietness warrants prompt veterinary contact. Rabbits can deteriorate quickly when they stop eating. Do not wait for a routine appointment or try human medicines. Keep a note of normal habits so changes are easier to spot. Dental disease can affect eating and should be considered when a rabbit becomes selective or drops food.

Scatter some of the daily forage or use safe feeding enrichment to encourage natural searching and movement. Make sure each rabbit in a group has access to hay and water without being displaced. Monitor individual intake and body condition, especially where several animals share a space. Keep feeding areas clean and protect hay from urine and damp bedding. A consistent diet and close observation help identify changes early, but they do not replace veterinary care when appetite or droppings change.

Guinea pigs share the hay-first pattern, but unlike rabbits they cannot make their own vitamin C and need a reliable daily source. Offer unlimited grass hay, a measured portion of plain pellets made for guinea pigs and used within their date, and daily vitamin C-rich vegetables such as bell pepper or leafy greens. Do not rely on vitamin C added to drinking water: it breaks down quickly and can put guinea pigs off drinking. Rabbit pellets are not a substitute.

Chinchillas also depend on constant hay for teeth and gut health, with a small daily ration of plain chinchilla pellets. Their digestion copes poorly with rich or sugary foods, so keep fresh greens, fruit, nuts and seeds very limited or absent, and change any food slowly. As with rabbits and guinea pigs, a chinchilla that stops eating or passes fewer droppings needs prompt veterinary advice.

Hay variety can encourage interest, but any new type should be introduced thoughtfully and should remain clean and dry. Store hay away from dampness, pests and strong odours. Check regularly for contamination before offering it. A rabbit that leaves food uneaten may have trouble reaching the feeder, competition from a companion or discomfort, not merely dislike. Observe feeding posture and access, and adjust the setup so each animal can eat without being chased away.

Avoid relying on a single indicator such as a full bowl. Check that water delivery works and that hay remains available throughout the day. A bottle can become blocked, while a bowl can be tipped or soiled; whichever is used must be checked and cleaned. In groups, provide multiple feeding points and observe individuals. If one rabbit’s intake is difficult to confirm, temporary supervised separation may help, provided it does not cause distress.

Offer hay in clean locations where every rabbit can reach it without competition. Check that racks are safely constructed and do not force an awkward posture. Observe whether each rabbit can chew and swallow comfortably; interest in food alone does not prove that intake is normal.
