But serving too much of lettuce is not an excellent choice to make. Guinea pigs do need a variety of vegetables in their daily diet so they can get all the nutrients necessary for their body.

Can guinea pigs eat lettuce every day?

Lettuce

Yes, guinea pigs can eat lettuce every day, but we must know which lettuce is to be fed.

Romaine lettuce and radicchio are high in nutrients but at the same time contain slightly high calcium in them which makes them unsuitable for daily consumption. 

Also, I did some surveys and found that some guinea pigs are found producing white pee when they are served with this type of lettuce while the others were fine. There is no concrete proof of why that happened.

However, green and red leaf lettuce contains just the right balance of nutrients and can be fed to our guinea pigs daily.

We had found no issues when the owners were serving this lettuce to their guinea pigs.

We must ensure that we help our guinea pigs with the appropriate quantity if we are serving it daily.

Serving lettuce in a high amount daily could be fatal in the long run.
