Best cheap hay for guinea pigs UK

A pair of Merino guinea pigs at nine months — lovely age, they're fully grown but still full of energy. One thing worth knowing before we dive in: guinea pigs are social animals and should always live in pairs or groups, so you're already doing that right. Space is the most underestimated need — most cages sold as 'guinea pig cages' are genuinely too small for two. But it sounds like you're sorted on the housing side and you're here about hay, which is actually the most important thing you'll buy for them. How many piggies, and is hay your main focus right now, or are you looking at food and enrichment too?

That's exactly the right question to ask. Cheap hay that's dusty or low in fibre is a false economy — it can cause respiratory problems and dental issues, which means vet bills that cost far more than decent hay ever would. The brand I recommend for your situation is Small Pet Select Timothy Hay. It's available on Amazon UK, it's dust-extracted, smells genuinely fresh, and has the high fibre content that keeps guinea pig teeth and guts healthy. It's not the absolute cheapest per bag, but the 1.5kg or 3kg boxes work out well per kilo and there's very little waste because the piggies actually eat it rather than picking through it.

It's genuinely well-regarded — Small Pet Select is the brand that small-animal vets and rescue centres in both the US and UK consistently point to when people ask for quality on a budget. It's not a premium luxury brand, it's just made properly: cut at the right time, stored well, no fillers. As for quantity, two adult guinea pigs should have unlimited hay at all times — it makes up about 80% of their diet. In practice, two piggies go through roughly 200–300g of hay a day depending on how much they nest in it versus eat it. The 3kg box on Amazon UK lasts around two to three weeks and typically comes in under £20. Subscribe and Save brings it down further if you want to lock in the lower price each month.

Honest answer: Burgess Excel Timothy Hay is the one I'd mention as a runner-up. It's widely available in supermarkets and pet shops as well as Amazon, which helps if you need it urgently. It's not quite as consistently fresh as Small Pet Select, and the cut is a bit coarser, but it's a solid hay and noticeably cheaper per kilo in larger bags. Avoid anything sold in a compressed brick or that smells musty in the bag — that's the hay that causes problems. If Small Pet Select is in your budget even occasionally, I'd use it as your main supply and treat Burgess as the backup when funds are tight rather than the other way around.
