Can Guinea Pigs Eat Spinach

Spinach is considered extremely healthy green leafy vegetable across the globe. Guinea pigs can eat baby spinach (it is something they prefer and good for them) and even the large leaves. But there is something that it contains which is harmful for their body which you need to be careful about. Read more to find out.

Can Guinea Pigs Eat Spinach

Yes, but not too much of it.

Spinach has double the amount of vitamin C compared to certain fruits. Since guineas cannot produce their own vitamin C, spinach is good for them. It has low sugar content adding to the advantage of serving them as sugar is bad for their health.

Spinach contains even vitamin A, low sugar and less calories which is good for maintaining the right balance in your cavy’s diet. It is like a super leafy vegetable but cannot be served daily to them.

 Spinach further helps with their overall eye health, elimination of free radicals, maintains good digestion, relieves constipation, helps to control weight, reduces blood pressure, aids the entire cardiovascular system, makes bones and teeth stronger thus boosting their entire immune system and keeping it healthy. This is how good spinach is for their health.  

But every vegetable has something that does not agree to a guinea pig. Spinach is rich in calcium and high in oxalic acid. And both are not good for them. Such foods with high oxalates lead to bladder stones, an issue commonly found in guinea pigs. These are painful and your cavy will need to undergo an operation to take the stones out. Spinach also results in blood clotting and this can be severely harmful for your cavy.

Can Guinea Pigs Have Spinach

Hence, spinach cannot be fed in large amounts. Feeding spinach in excess amounts will lead to serious health issues and maybe even result in death for some guineas.

Guinea pigs love to eat spinach and to some extent it is safe but in moderation. 2-3 leaves once a week is exactly right. Choose the leaves that are darker green and not yellow or rotten.

 Leafy veggies like spinach need to be washed thoroughly because pesticides are sprayed on them to keep fresh. If these are ingested by your cavy, it can prove fatal. Separate the stalks as it is tough for them to eat those (also choking hazards). Organically grown spinach is the best to serve them. Clean up the leftovers after they are done eating to avoid bacteria blooming.
