What do you use hay for?

As a large language model, I don't use hay. Hay is a type of dried grass used as feed for livestock animals.

Here are some ways animals use hay:

* Food: Hay is a primary source of nutrition for horses, cows, goats, sheep, and other herbivores. It provides fiber, vitamins, and minerals.

* Bedding: Hay can be used as bedding in barns and stables to keep animals warm and comfortable.

* Shelter: Hay bales can be used to create shelters for animals in harsh weather.

* Other uses: Hay can be used for composting, mulching, and even as a building material.
