The Rat Diet: Can Rats Eat Timothy Grass?


Rats make great pets, and their diet is crucial for their overall health and wellbeing. While their primary food source should be a quality commercial rat food, it is important to provide them with a varied diet to meet their nutritional needs. Timothy grass is a commonly used feed for other small animals like guinea pigs and rabbits, but can rats also indulge in this type of grass? Let’s find out!

What is Timothy Grass?

Timothy grass, also known as Timothy hay, is a type of forage grass commonly used as food for herbivorous animals. It is low in protein and calcium but high in fiber, making it an excellent option for small herbivores. Guinea pigs, rabbits, and horses are commonly fed Timothy grass as it supports their gastrointestinal health and provides a natural source of roughage.

Can Rats Eat Timothy Grass?

Yes, rats can consume Timothy grass without any major issues. It is safe for them to eat, and some rats even enjoy nibbling on the grass. However, it is important to note that Timothy grass should never replace the main portion of a rat’s diet, which should consist of a balanced and commercially formulated rat food. While Timothy grass provides fiber, it lacks many essential nutrients that rats require for their overall health.

Benefits of Timothy Grass for Rats

Although Timothy grass should not be the primary food source for rats, incorporating it into their diet can provide some benefits. The high fiber content helps keep their digestive system healthy and prevents gastrointestinal issues. Chewing on Timothy grass can also help wear down their teeth, which continuously grow throughout their lives. Additionally, rats enjoy foraging and exploring new textures, so offering a small amount of Timothy grass can provide them with mental stimulation.

Precautions and Guidelines

While Timothy grass is generally safe for rats, there are a few precautions to keep in mind:

1. Quality and freshness: Ensure that the Timothy grass you provide to your rats is fresh, free of mold, and not contaminated by pesticides or other chemicals.

2. Moderation: Timothy grass should be given as an occasional treat or supplemental feed rather than a significant portion of their diet. A few sprigs or small handfuls once or twice a week are sufficient.

3. Monitor digestion: If you notice any signs of digestive upset, such as diarrhea or bloating, after introducing Timothy grass to your rats’ diet, it is best to discontinue feeding it.

4. Variety and balance: Remember that rats need a varied diet to get all the necessary nutrients. Along with their commercial rat food, provide them with a mix of fresh vegetables, fruits, and occasional treats like Timothy grass for a well-rounded diet.


Timothy grass can be a safe and enjoyable addition to your rats’ diet, albeit in moderation. While it offers some benefits like promoting digestion and providing mental stimulation, it should never replace their primary rat food. As responsible pet owners, it is essential to ensure a balanced and nutritious diet to keep our furry friends happy and healthy for years to come.
