Here's why:
* Different nutritional needs: Horses and guinea pigs have vastly different dietary needs. While timothy hay is a good source of fiber for horses, it's not a suitable staple for guinea pigs.
* Higher calcium content: Horse timothy cubes often have a higher calcium content than what guinea pigs need. This can lead to urinary stones and other health problems.
* Lack of essential nutrients: Horse timothy cubes may not contain the essential vitamins and minerals that guinea pigs require for optimal health.
* Potential for choking: The larger size of the cubes can be difficult for guinea pigs to chew and swallow, potentially leading to choking.
Instead of horse timothy cubes, provide your guinea pig with:
* Timothy hay: This is the best staple hay for adult guinea pigs.
* Other hay options: You can also offer oat hay, orchard grass hay, and meadow hay in smaller amounts.
* Fresh vegetables: Offer a variety of leafy greens and other vegetables daily.
* Guinea pig pellets: Choose a high-quality pellet specifically formulated for guinea pigs.
It's always best to consult with your veterinarian for personalized advice on your guinea pig's diet.
