Timothy vs. Orchard: Your Guinea Pig’s Perfect Hay

Choosing the right hay is necessary for the overall well-being of a guinea pig. As 80% of their diet consists of hay, so choosing the best hay for your pet is important. A good quality hay is not only tasty for the piggy but also affects their delicate digestive system and ever-growing teeth.

Timothy hay and orchard grass are two of the most popular products that piggy owners love to feed their furry companions. Both of them have a few similar features, so new piggy parents may wonder which is best for their beloved piggy.

Here I have compared Timothy hay and orchard grass to determine which one reigns supreme for the tiny rodents. 

Why is hay essential for guinea pigs?

Hay is considered life and death for piggies. Here’s why it is non-negotiable.

Dental health 

As you know, the teeth of guinea pigs grow continuously. So, to wear them naturally, the only way is to chew coarse hay for hours daily. Your piggy may suffer from misaligned teeth and painful overgrowth if they are not given sufficient hay to chew. 

Good digestive health

Hay contains indigestible fiber that prevents deadly conditions like GI stasis and keeps their delicate digestive system moving.

Promotes better mental health

Foraging through hay prevents boredom and provides mental stimulation. This keeps your piggy active and happy.

Which hay is better for your piggy?

  • Healthy adult piggy: The superior dental wear and perfect balance of timothy hay make it ideal for healthy adult piggies.
  • Sensitive or picky eater: Orchard grass is the winner for older piggies who are picky or sensitive. It is more gentle and palatable than Timothy.
  • Young piggies (under 6 months old): Even though the young pups need alfalfa hay, gentle orchard grass can also be fed slowly. As they approach adulthood, introduce them to Timothy gradually.
  • Piggies with dental issues: Often, the softer 2nd cut timothy is recommended for piggies with dental issues. Being less abrasive, orchard grass can be easier for them to eat initially. Consult your vet to find out the best grass for your furry companion.
  • Mixing both grasses: Often, experts suggest mixing Timothy and orchard grass to feed to your guinea pigs. This offers dental benefits, keeping picky eaters interested due to the palatability of orchard grass. A 50/50 or 70/30 mix ensures balanced nutrition and variety in texture/taste.

Tips for choosing the best hay for piggy perfection

  • Quality: Always buy fresh-smelling, green hay. Yellow, dusty, brown, and musty hay should be avoided.
  • Unlimited supply: Guinea pigs need constant access to hay. So, refill hay racks several times a day. To encourage natural foraging, place a pile on the cage floor.
  • Storing is important: avoid sealing the hay tightly in plastic bags as it can cause mold, as plastic bags trap moisture. Always keep the hay in a dark, dry, and cool place inside a breathable container like a well-ventilated bin or cloth bags.
  • Transition should be done gradually: mix the new and old hay together. To avoid digestive upset, gradually increase the new type over 7 to 10 days.

Recap

Both Timothy hay and orchard grass can be included in your guinea pig’s primary diet. Timothy is best for senior and healthy, adult piggies who need to robust their dental wear. On the other hand, orchard grass can be a good option for picky eaters, young pups, and senior piggies struggling with tougher hay. 

Unlimited high-quality hay provides the best foundation for the happy, healthy, and long life of your furry companion.
