Quick Picks
Hay is not the boring part of a guinea pig diet, it is the whole foundation. Guinea pig teeth grow non-stop, and chewing long-stem grass hay is what keeps them worn down to a healthy length. Hay also keeps the digestive system moving, which matters because guinea pigs have a delicate gut that stops working properly when fibre intake drops.
The problem UK owners face is not whether to feed hay, it is which hay to buy. Supermarket bags can arrive brown and dusty, premium imports cost a fortune, and every brand claims to be the one your guinea pig will love. We compared six hay options available on Amazon UK, looking at hay type, dust levels, value for money and what Amazon reviewers with guinea pigs actually report after using them. Our comparison is based on Amazon purchaser reviews, manufacturer specifications and independent feedback.
One rule applies to everything below: whatever you buy, your guinea pig needs unlimited access to fresh grass hay every single day, with nuggets and vegetables on top, not instead.

In-Depth Reviews
1. Oxbow Western Timothy Hay 1.13kg
Timothy grass hay | 1.13kg | Imported | Soft and leafy
Oxbow is a well-known hay brand, and its Western Timothy Hay is the standard many owners measure other hays against. Timothy is a grass hay, which means it is naturally lower in calcium and protein than legume hays like alfalfa, so it suits adult guinea pigs that need a high-fibre, low-extra-nutrient diet. The 1.13kg bag is cut leafy and soft, which guinea pigs tend to eat more readily than stalky, woody bales.
Amazon reviewers with fussy guinea pigs note that this hay is consistently green and sweet-smelling, with very little dust and few brown stalks. That consistency matters, because guinea pigs can be stubborn about hay they do not like, and a bag that smells stale or looks brown can be ignored entirely. The main downside is the price, because imported US timothy costs more per kilo than UK meadow hay.
If you want a dependable premium hay and your guinea pigs eat it without waste, Oxbow is a strong daily choice. It is also a good option for owners who buy from Amazon rather than local suppliers, because the sealed bag keeps the hay fresher than loose bale alternatives.
- Consistently green and leafy
- Very low dust for a loose hay
- Well accepted by fussy eaters
- Strong resealable packaging
- Pricier than UK meadow hay
- Smaller bag than value options
- Imported, so higher carbon footprint
2. Supreme Science Selective Timothy Hay 2kg
Timothy grass hay | 2kg bag | From the Science Selective brand | Value for money
Supreme Petfoods is the UK company behind Science Selective guinea pig nuggets, so this timothy hay comes from a brand that already understands small herbivore nutrition. The 2kg bag undercuts most premium timothy options on price per kilo while keeping the timothy grass base that adult guinea pigs need. It is a straightforward, no-fuss hay with no added flavours or colourings.
Amazon reviewers highlight the bag size and the value, with several noting it lasts a single guinea pig several weeks when used alongside fresh vegetables. The hay is described as drier and more stalky than the Oxbow option, which is not a bad thing for dental wear, though very fussy pigs may leave some of the coarser stems. Check the batch when it arrives, because quality can vary between cuts.
For owners with one or two guinea pigs who want a decent timothy hay without the premium import price, this is the best balance of quality and cost in this list. It also pairs well with the Science Selective nugget range if you already feed that brand.
- Cheaper per kilo than most timothy hays
- Well-known UK brand
- 2kg bag lasts well
- Good all-round grass hay
- Can be stalkier than premium options
- Quality varies a little between cuts
- Not dust-extracted
3. Extra Select Premium Meadow Hay 1kg
Meadow hay | 1kg | UK sourced | Budget friendly
Extra Select is a budget-friendly UK-sourced meadow hay. Meadow hay is cut from mixed grasses and wild plants rather than a single grass type, which gives guinea pigs variety in texture and taste. For owners who go through hay quickly, this is the kind of product you can buy without wincing at the basket total.
Amazon reviewers describe it as decent everyday hay that most guinea pigs eat happily, with the caveat that colour and softness vary from batch to batch depending on the season it was cut. A 1kg bag is a sensible size for finding out whether your guinea pigs will accept it before you commit to a bigger bale from a local farm shop.
UK-sourced hay also tends to be fresher than imported options because it spends less time in transit. If your guinea pigs are not fussy and you want an affordable daily hay, this is a sensible pick, and it works well as a top-up between premium bags.
- UK sourced and fresh
- Cheap enough for daily feeding
- Mixed grasses add variety
- Good starter size
- Batch quality varies with season
- Not dust-extracted
- Small 1kg bag for the price
4. Norfolk Pastures Dust Extracted Hay XL pack
Dust-extracted hay | XL pack | UK | Low dust for sensitive airways
Norfolk Pastures specialises in dust-extracted hay, which is shaken and filtered to remove the fine particles that can irritate guinea pig airways. Dust is a real concern for indoor guinea pigs, because their respiratory systems are sensitive and dusty hay can trigger sneezing, runny eyes and worse in pigs already prone to chest problems.
Amazon reviewers who switched to dust-extracted hay report noticeably less dust in the hay rack area and fewer sneezing episodes in sensitive guinea pigs. The XL pack suits multi-pig households, though it is worth storing it in a dry, breathable container because dust-extracted hay still needs proper airflow to stay fresh.
If your guinea pigs live indoors, share a bedroom with you, or have any history of respiratory trouble, the extra cost of dust-extracted hay is easy to justify. It is the kind of product you buy for peace of mind as much as for the hay itself.
- Very low dust, better for airways
- XL pack suits multi-pig homes
- UK producer
- Good for indoor setups
- Costs more than standard meadow hay
- XL pack needs dry storage
- Fewer reviews than big brands
5. Burgess Excel Forage Dried Grass 1kg
Dried grass | 1kg | Burgess Excel brand | Soft texture, low dust
Burgess Excel Forage is dried grass rather than hay, which means it is cut younger and dried quickly, leaving it softer, greener and lower in dust than mature hay. Burgess is one of the biggest UK small-animal food brands, and this product is aimed squarely at owners whose guinea pigs waste loose hay or who want a cleaner option for indoor feeding.
Amazon reviewers like it for guinea pigs that are picky about stalky hay, and several use it as a travel option or a backup when their usual hay supply arrives brown. Because it is softer, it provides less coarse chewing than mature hay, so it works best as part of the diet rather than the whole diet.
Think of dried grass as a useful supplement that keeps fibre intake up when hay quality dips or when you are away from home. It does not replace the dental wear of proper long-stem hay, so keep offering loose hay alongside it.
- Soft, green and low dust
- Well accepted by picky eaters
- Trusted UK brand
- Handy backup or travel hay
- Softer, so less dental wear than hay
- Should not replace loose hay entirely
- 1kg bag goes quickly
6. Kaytee Natural Timothy Hay Cubes 453g
Compressed timothy hay cubes | 453g | Long-lasting | Minimal mess
Kaytee timothy hay cubes are compressed blocks of timothy hay, and they solve two common owner complaints at once: waste and mess. Loose hay gets dragged around cages, soiled and thrown out, while cubes sit in the bowl and get gnawed down slowly. They are 100% timothy with nothing added, so they are nutritionally the same as loose timothy hay.
Amazon reviewers use cubes for travel, for topping up between loose-hay deliveries, and for guinea pigs that prefer something to grip while they chew. The gnawing action is excellent for keeping teeth worn down. The trade-off is that cubes do not give the same foraging experience as loose hay, and some guinea pigs need a few days to figure them out.
Cubes are best treated as a supplement to loose hay rather than a full replacement. Keep a bowl of loose hay available and offer cubes as a long-lasting extra, and you get the best of both.
- Very little mess or waste
- 100% timothy, nothing added
- Excellent for dental wear
- Great for travel and top-ups
- Not a foraging experience like loose hay
- Some guinea pigs ignore them at first
- Costlier per kilo than loose hay
How to Choose Guinea Pig Hay
Feed grass hay, not legume hay. Timothy, meadow and orchard grass are all grass hays and are right for adult guinea pigs. Alfalfa is a legume hay with much higher calcium and protein, which is useful for growing and pregnant guinea pigs but too rich for adults to eat freely. Check the label, because some cheap mixes contain alfalfa or clover.
Look at the colour and smell before you commit. Good hay is greenish, smells sweet and grassy, and feels dry. Yellow or brown hay, hay that smells musty, and bags that puff out dust when you squeeze them are all signs of poor storage or an old cut. If the first bag from a brand disappoints, try another batch before writing the brand off, because quality changes between cuts and seasons.
Match the hay to your setup. Indoor guinea pigs and pigs with any history of respiratory trouble do better with dust-extracted hay like the Norfolk Pastures option, because fine dust particles are the main irritant. Outdoor guinea pigs with healthy lungs can handle a good standard hay and will happily eat cheaper UK meadow hay.
Buy sensibly, store carefully. Hay is bulky and cheap per kilo in big bales, but a bale only works if you can store it dry with some airflow. In a damp British flat, a 2kg Amazon bag with resealable packaging is often more practical than a farm bale. Always store opened hay away from damp and check each new batch before feeding.
Watch what your guinea pigs actually eat. The best hay in the world is useless if your guinea pigs ignore it. Offer a small amount of a new hay alongside their current one and see which they finish first. Some pigs prefer soft leafy hay, others like coarser stems to grind on, and it can take a few tries to find the match.
Frequently Asked Questions
Final Verdict
For most UK owners, Oxbow Western Timothy Hay is the best all-round choice: consistent, low-dust and reliably accepted by guinea pigs, which is exactly what you want in a daily hay. If the price makes you wince, the Supreme Science Selective 2kg bag gives you solid timothy at a much friendlier cost per kilo.
Indoor owners should seriously consider dust-extracted hay, because cleaner air matters more than a few saved pounds when a guinea pig already lives in a bedroom. And keep a bag of timothy hay cubes in the cupboard for travel days and emergency top-ups.
Whatever you pick, the non-negotiables stay the same: fresh grass hay available around the clock, stored dry, and topped up before the rack runs empty. Get that right and you have already done more for your guinea pig's teeth and digestion than any supplement on the shelf.
