Can Iguanas Eat Brussel Sprouts?

Brussel sprouts are safe for iguanas and you can feed them in moderation. In larger amounts, they can cause problems, but are otherwise a healthy addition to your pet’s diet.

Iguanas are herbivores, and their diet should consist entirely of leafy greens, vegetables, and fruits.

Brussel sprouts are a good source of fiber and vitamins, including vitamin C, vitamin K, and potassium.

They should however only be fed in limited amounts, as they can limit a reptile’s ability to absorb calcium in larger amounts.

Brussel sprouts are members of the cabbage family, and cabbage family vegetables contain compounds called glucosinolates.

When glucosinolates are broken down by enzymes in the digestive system, they produce compounds called thiocyanates.

Thiocyanates can bind to calcium and make it less available to the body.

Reptiles have a more difficult time breaking down glucosinolates than mammals. This is because reptiles have a slower digestive system and less stomach acid.

As a result, iguanas are more likely to be affected by the calcium-binding effects of thiocyanates.

In addition to thiocyanates, brussel sprouts are also high in oxalates. Oxalates can also bind to calcium and make it less available to the body.

For these reasons, it is important to feed iguanas brussel sprouts in moderation.

A good rule of thumb is to offer no more than 10% of your iguana’s diet in cabbage family vegetables.

You should also offer your iguana other calcium-rich foods, such as collard greens, kale, and mustard greens.

Consider dusting your iguana’s food with a calcium supplement and reptile-safe multivitamin a couple of times a week.

Feeding brussel sprouts to iguanas

You may feed fresh or frozen brussel sprouts to your pet iguana.

Cooking is not necessary, but you can steam or blench the sprouts briefly to make them easier to digest. Chopping them into smaller pieces will also make them easier to eat.

Here’s how you can prepare brussel sprouts for your lizard:

  1. Wash the brussel sprouts thoroughly. Remove any dirt or debris from the brussel sprouts.
  2. Remove any tough outer leaves and stems. Cut off any tough outer leaves and stems from the brussel sprouts.
  3. Chop the brussel sprouts into small pieces. Cut the brussel sprouts into pieces that are about the size of your iguana’s head.
  4. Steam or blanch the brussel sprouts. Place the brussel sprouts in a steamer basket and steam them for 2-5 minutes, or until they are soft but not mushy. Alternatively, you can blanch the brussel sprouts by boiling them for about 2 minutes, then immediately plunging them into ice water.
  5. Offer the brussel sprouts to your iguana. Place the brussel sprouts in your iguana’s food dish and offer them to them. You can also sprinkle the brussel sprouts with a calcium supplement to help your iguana absorb the calcium in the brussel sprouts.
