How Much Hay an Indoor Rabbit Actually Eats

This is simple. Rabbits need unlimited hay every day. Not a measured cup, not “a handful,” not whatever is left in the rack from yesterday. Unlimited.

A good visual estimate: a pile about the size of the rabbit’s body, refreshed daily. Most indoor rabbits will go through roughly 3–5 ounces of hay per 5 lbs of body weight per day, but watching intake is more reliable than measuring.

Signs they’re getting the right amount:

  • Firm, round droppings

  • Consistent eating throughout the day

  • Little to no mushy stool

  • Good appetite at pellet time without acting frantic

If you notice reduced hay consumption, check:

  • Freshness (must smell sweet, never dusty or sour)

  • Placement (offer in litter box and another spot)

  • Dental comfort (reduced hay eating can signal dental issues)

Hay storage for indoor homes:

  • Keep in a cool, dry place

  • Use breathable containers (no sealed bins unless vented)

  • Rotate stock so the oldest hay is used first

In short: always available, always fresh, always plenty. When in doubt, offer more.
