Can Rabbits Eat Zucchini?

Yes, rabbits can have zucchini, and there’s very little prep required.  

Green zucchini, yellow zucchini, and other common summer squash varieties are all OK as long as they’re fresh and plain. 

You can leave the skin on too—it’s perfectly fine for rabbits to eat and saves you a step. The small, soft seeds inside are safe as well, so you don’t have to scoop those out like you would with some other fruits and veggies. 

Skip fried zucchini, zucchini bread, muffins, zucchini noodles with sauce, casseroles, and zucchini cooked with salt, oil, butter, garlic, onion, cheese, or creamy sauces. These extra ingredients can be bad for your bunny. 

If you don’t want to pull out the cutting board, rabbit treats made with veggies can be an easier way to switch things up. Try one of these options: 

Zucchini isn’t a nutritional must-have for rabbits, but it has a few things going for it. It’s mostly water, relatively low in sugar, and easy to work into the mix of fresh veggies your bunny already eats.  

The main benefits are: 

• Hydration: Zucchini has a high water content, so every bite provides a little extra moisture alongside your rabbit’s fresh water. 
• Some fiber: Zucchini contains fiber that contributes to healthy digestion, although it has nowhere near enough to replace the fiber your rabbit gets from hay. 
• Vitamins and minerals: Zucchini provides potassium, an important mineral that helps support normal muscle, nerve, and heart function. It also contains vitamin C, although rabbits make their own and don’t need to get it from food. 
• Variety and enrichment: Zucchini’s crisp, juicy texture gives your bunny something a little different to nibble on, and its mild flavor makes it easy to pair with other rabbit-safe veggies. 

A zucchini-heavy meal can leave your bunny with an unhappy stomach and less room for the hay they really need. 

Here’s where you can run into trouble: 

• Too much zucchini: A big serving of zucchini—or too much too soon if it’s a new food—may cause gas, bloating, soft stool, diarrhea, or changes in appetite. 
• Less room for hay: Zucchini contains some fiber, but it can’t take the place of hay. If your rabbit fills up on veggies and eats less hay, they miss out on the fiber that keeps food moving through their digestive tract. Without enough fiber, digestion can slow or stop, potentially leading to GI stasis, a serious condition that can become life-threatening without treatment. 
• Unsafe preparations: Fried zucchini, casseroles, zucchini bread, and sauced zucchini noodles can contain oil, butter, salt, sugar, dairy, garlic, onion, or other ingredients your rabbit shouldn’t be eating. Set aside your bunny’s portion while the zucchini is still raw and plain. 
• Spoiled zucchini: A bruised spot you can trim away is one thing; zucchini that’s slimy, moldy, rotten, or smells off can make your rabbit sick. 

You don’t need to split an entire zucchini with your bunny. Two or three thin, bite-size slices three to four times per week is enough for most adult rabbits. 

It’s best to mix zucchini with other rabbit-safe veggies rather than piling several slices into the bowl at once. And while your bunny may happily come back for seconds, save most of that appetite for hay. 

Zucchini doesn’t need much fussing before it’s ready for your bunny. Here’s how to prep it to make sure it’s safe:  

• Choose fresh zucchini. It should feel firm and look fresh, without slimy, moldy, or rotten areas. 
• Wash it well, especially if you’re serving it with the skin on. 
• Cut away soft or bruised spots. 
• Slice off a few small pieces. 
• Serve it raw and plain. 
• Remove uneaten zucchini before it starts getting soft or spoiling in your rabbit’s enclosure. 

If your rabbit managed to eat more zucchini than you intended, don’t offer any more and make hay the focus for the rest of the day. Keep an eye on their appetite, behavior, and poop so you can catch any signs that their stomach isn’t happy. 

Call your veterinarian if you notice: 

• Diarrhea or very soft stool 
• Gas or a bloated belly 
• Eating less than usual 
• Fewer or no droppings 
• Low energy 
• Teeth grinding 
• Signs of pain or discomfort 

If your rabbit stops eating or pooping altogether, call your vet right away. These can be signs of GI stasis. If your regular vet isn’t available, head to an emergency clinic that treats rabbits. 

If the zucchini was part of a dish containing potentially harmful ingredients, such as garlic or onion, you can contact the Pet Poison Helpline (855-764-7661) for advice on next steps. 

If zucchini goes over well, there are plenty of other bunny-safe veggies and herbs you can add to the mix too. 

Some options include: 

• Arugula 
• Basil 
• Bell peppers 
• Brussels sprouts 
• Carrots 
• Celery 
• Cilantro 
• Green beans 
• Kale 
• Lettuce 
• Parsley 

Switching up the type of veggies you offer gives your bunny different flavors and textures to explore. But no matter what you pull from the produce drawer, make sure there’s always plenty of grass hay available. 

Not right away. Wait until your rabbit is at least 12 weeks old and doing well with appropriate fresh greens before giving them zucchini. When it’s time for their first taste, start with one tiny piece and see how their stomach handles it before giving them more. 

Yes, rabbits can eat zucchini with the skin on—just give the outside a good wash before you slice it up.  

Yes, rabbits can eat plain, cooked zucchini, but there’s really no reason to cook the veggie for your bunny. They can eat it raw, and serving it that way means you don’t have to worry about extra ingredients, like butter, oil, salt, garlic, or onion, that often get added during cooking. 

No. There may be zucchini in the name, but zucchini bread is still bread. The sugar, flour, fat, and other ingredients make it a poor choice for rabbits, so save this one for the humans.
