Hay can be placed in sleeping areas, but it should not replace proper bedding materials. Guinea pigs need absorbent bedding such as paper-based or fleece liners to keep their enclosure dry and hygienic. Hay should primarily be provided as food, and any soiled hay should be removed daily to maintain a clean living environment.
Yes, guinea pigs can safely eat Meadow Hay. However, because it can vary in texture and nutritional balance, many owners use Meadow Hay alongside Timothy Hay rather than as the sole source of hay.
Straw should not replace hay in a guinea pig’s diet. Straw is lower in fibre and much tougher, making it difficult to digest. While small amounts of straw can sometimes be used for bedding or extra warmth, it does not provide the essential nutrition guinea pigs need. Always provide unlimited access to fresh, high-quality hay instead.
