* Fiber, Fiber, Fiber: Hay is the cornerstone of a guinea pig's diet. It's incredibly high in fiber, which is crucial for their digestive system to function properly. Fiber helps:
* Promote regular bowel movements: Prevents constipation and keeps their digestive tract moving smoothly.
* Maintain healthy teeth: Guinea pig's teeth grow continuously. Chewing on hay helps to wear them down and prevents overgrowth, which can be painful and dangerous.
* Control weight: The high fiber content keeps them feeling full and helps prevent obesity.
* Essential Nutrients: Hay provides a wide range of vitamins and minerals crucial for their overall health.
* Natural Instinct: Guinea pigs are herbivores, and their digestive systems are designed to process a high volume of roughage. Hay replicates their natural diet in the wild.
* Mental Stimulation: Chewing hay provides mental stimulation and helps to keep them occupied, especially when they're alone.
What type of hay is best?
* Timothy Hay: The most recommended type, especially for adult guinea pigs. It's lower in calories and higher in fiber.
* Oat Hay: Can be offered as a treat, but should be given in moderation as it's higher in calories.
* Alfalfa Hay: Good for growing piggies (under 6 months old) due to its higher calcium content, but too much can cause bladder stones in adults.
How much hay should they eat?
Guinea pigs should have unlimited access to hay at all times. A good rule of thumb is to provide at least 1/2 cup per day per guinea pig.
Important Note: While hay is essential, it's not a complete diet. Guinea pigs also need a balanced diet that includes fresh vegetables, a small amount of high-quality guinea pig pellets, and vitamin C supplements.
