Extra Hay From Oxbow for Young and Pregnant Piggies

Oxbow Western Timothy is ideal for adult guinea pigs BUT:

It’s not nutrient-rich enough for young guinea pigs or pregnant/nursing sows!

If your guinea pig fits this description, then also order them a bag of No products found... you should feed them both types (Timothy and alfalfa) to give them the extra protein, calcium, and fat!

Nobody — they’re currently the undisputed guinea pig food champions!

Oxbow Essentials Adult Guinea Pig Food is our favorite product from the company and one we whole-heartedly recommend to anyone with a guinea pig over 6 months old!

Looking for a more affordable source of timothy hay for your pet guinea pig?

What’s our favorite thing about it?

Manufacturers Specs and Features

  • FEEDING DIRECTIONS: Standlee recommends selecting a commercial fiber-based, vitamin and mineral fortified food, like PremiYum fortified food, and pair it with high-quality, hand-selected long-stem forage. Timothy Grass is NOT intended to be the only component of the diet. Place forages in a hopper or bin to prevent spoilage. Remove any uneaten forage if it becomes wet, damp, or soiled.
  • STORAGE AND SHELF LIFE: Proper storage includes keeping the product dry and unexposed to the elements. Simply reclosing our specially designed box helps keep our forages dry and free from contamination. Instructions on how to reclose the box are printed on the top flap.
  • HEALTHY DIGESTIVE SYSTEM: Feeding a small amount of fresh forage stimulates chewing, which aids in proper teeth wear and promotes a healthy digestive system.


  • Great price
  • Good source of fiber — necessary for a healthy gut!
  • Aromatic
  • All-natural
  • 100% additive-free
  • Low in protein and calcium

Extra Foods You NEED — Fresh Fruits and Vegetables

No matter what hay and pellets you pick, there’s one thing you have to get your guinea pig:


Guinea pigs love:

  • Romaine lettuce
  • Sweet potatoes
  • Kale
  • Carrots
  • Zucchini
  • Tomatoes
  • Cucumbers

Don’t bother pre-ordering these veggies online; get them super fresh from your local supermarket or greengrocer!

You can also occasionally buy a piece of fruit (like an orange or an apple) to give them as a tasty snack — but don’t overdo it as fruits are too high in sugar to be a regular part of their diets.

Here, we’ll answer seven FAQs we hear all the time from guinea pig owners and fast-track your knowledge about what guinea need to eat to live long and happy lives!

Let’s dive in.

What Should You Check for in Guinea Pig Foods?

Make sure the foods you pick are:

  • Made from high-quality, natural ingredients
  • High in vitamin C as guinea pigs cannot naturally produce their own
  • Rich in grass hay that’s high in fiber to support their digestive systems and dental health
  • Fortified with probiotics and omega-3 fatty acids

  • Animal products (like meat and dairy)

What Are the Best Guinea Pig Food Brands?

At the moment, our picks for the top three brands are:

  1. Oxbow (first by a mile)
  2. Kaytee
  3. Small Pet Select

What Types of Guinea Pig Food do You Need?

Make sure to feed your guinea pigs these types of food:

  • Tons and tons of fresh hay — it’s the best way to keep their teeth healthy and provide a source of natural, high-fiber food.
  • Pellets — they’re an excellent supplement because they’re rich in vitamins and minerals.
  • Veggies — another fantastic, nutrient-rich supplement that also tastes great.
  • Treats (pre-packaged or fruit)— they’re the secret to giving your guinea pig a moment of pure bliss.

But how often should I feed my guinea pig, and how much?

Good question — read on and find out!

How Much Food Should I Give My Guinea Pigs? And How Often?

Let’s break it down by time period.

On a daily basis:

  • An unlimited amount of hay—Your goal is to get your guinea pigs to eat a high-fiber diet made up of 70-75% hay. Timothy is ideal for an adult guinea pig, while an alfalfa/timothy mix is best for a young guinea pig or a pregnant/nursing sow.
  • Around 20-40 grams of pellets— remember that these are supplements, not their main food!
  • A similar amount of fresh vegetables (30-50 grams)— 3 different types of veg per day are best.
  • Unlimited water —get your guinea pigs a water bottle and keep it full always!

On a bi-weekly basis:

  • Yummy treats like a piece of fruit or a tab/biscuit.


Don’t overfeed your guinea pigs, or else you could cause them unwanted health issues!

Can Guinea Pigs Only Eat Pellets?

No, definitely not!

Pellets are an integral part of a guinea pig’s diet, but they need a wider diversity of foods to ensure they get all the nutrients their little bodies need.

So keep pellets at around 10-20% of their daily food intake!

What Should I Do if My Guinea Pig Won’t Eat Their Pellets?

Don’t worry — sometimes it happens that a picky cavy doesn’t want to eat their pellet food.

Try one of these two strategies.


Mix some of the pellets they won’t eat with the ones you’re trying to phase out. Aim for a total of about 10-15% new food. This should be enough to convince your fussy munchkin to chow down!

Then, every day, increase the ratio by about 10% until you’re only feeding your guinea pig the new pellets!

This strategy also prevents digestive issues when switching pelleted foods.


Give up and turn to a different brand of pellets.

Your pet guinea pig might have gotten bored of the taste or simply never liked them much.

Can I Feed My Guinea Pigs Cat Food, Rabbit Food, or Dog Food?

No, pet foods aren’t generic! Only feed your guinea pigs specially formulated foods to guarantee they contain the right nutritional value.

Conclusion: The Best Guinea Pig Food
